[[caption-width-right:200:And these are the Protagonist's relatives! Imagine the rest of the girls in the story...[[labelnote:*]]''(From left)'': Asahi Momozono and Kaoruko Fujiwara, his cousin and aunt, respectively.[[/labelnote]]]]

-> ''The goal of my research is to get a deeper understanding of "TheTaleOfGenji", and for that, I need someone who understands what Prince Genji went through.''
--> - '''Kaoruko Fujiwara'''

A modern-day re-imagining of TheTaleOfGenji by Inaba Minori. Terumi Minamoto is a young man [[{{Bishonen}} with a face pretty enough to make people think he is a girl]]. During his middle school years, Terumi was bullied by [[GangOfBullies women who were jealous of his face]] and as a consequence, developed a fear of women, to the point of attending an all-boys high school to escape his trauma.

Prior to attending Shiun University, however, he decides to overcome this fear and become someone [[TheCasanova who can have sex with any woman he wants]] but almost immediately after deciding this, his father informs him that he is remarrying and that since their apartment is only big enough for two people, Terumi needs to move out. Terumi's father arranges for him to move in for the time being with his aunt, Kaoruko Fujiwara.

Kaoruko just happens to be one of the most beautiful women in the university, who has done much literary work using TheTaleOfGenji as a base, and is admired and respected by people of both genders. When Terumi arrives at her apartment, she quickly guesses that he was bullied due to his face and that he doesn't have any experience with women. Thinking it would be too boring for him to just lounge around the apartment she offers to help him get over his fear, in exchange of becoming her guinea pig for her research in her "[[GenderFlip Reverse]] [[WifeHusbandry Hikaru Genji Plan]]".

Helping him have sex with 14 women shouldn't be too much trouble...right?

!! Minamoto-kun Monogatari contains general examples of:
* AllMenArePerverts: Terumi tries to deny that this trope applies to him but the audience knows better. Men like Murakami and Konoe are less subtle about it. There are also all the men that gawk at Kaoruko, Aoi and Rokujou.
* AllWomenAreLustful: Just because Terumi gets horny doesn't mean the women don't get horny too:
** Kaoruko regularly offers her body to Terumi to get him used to the idea that men aren't the only ones who have sex on their mind.
** Asahi reads perverted manga and masturbates to Terumi after her first sexual experience. Reading a erotic novel highlighting a relationship between cousins only reminds her of the ordeal.
** Aoi treats Terumi as a sex toy and mentions during their time together that her "switch" was turned on...
** Hanada is fearful of men but her time with Terumi has caused her to slowly get over that fear. The thought of Terumi touching her sexually gets her excited.
** Rokujou is ''really'' interested in Terumi and, like Asahi, masturbates to him, this time with a old middle school picture nearby.
** Semi is happy that Terumi is paying attention to her and respecting their time together. She becomes even happier when Terumi becomes aroused despite her age.
** Yuu is desperate for a lover and is becoming more and more open to the idea of pursuing a relationship with Terumi as time passes. She even wonders to herself if she has some repressed desires, despite never experiencing sex, let alone a kiss.
** Tsukasa is excited at pursuing a [[TeacherStudentRomance forbidden relationship with Konoe]] and gets hot and bothered when Terumi stands up to her and gives her a steamy kiss.
** Tsukiko becomes giddy whenever she observes Terumi attempting to talk with women or is having struggles with his sexual tensions. Being a erotic novelist in training helps too.
* CharacterDevelopment: Terumi and the characters that he interacts with all go through slow but drastic changes over time:
** Terumi himself no longer freaks out as much around women at large, including his nemesis and cause of his fear, Tsukasa. He is finding it easier to talk with women, becomes more experience with foreplay that eventually leads to sex and is becoming more confident over time.
** Asahi and Tsukiko both think men are pigs with nothing but sex on their minds. While they may be right about the majority of men in this manga, Terumi is the one exception they find no problem talking to. Asahi herself is falling for Terumi over time despite their relations as cousins and Tsukiko relies on Terumi in order to bolster her writing as an erotic novelist, as well as acting as friendly confidant to Terumi.
** Aoi's complex towards her father complicates any relationship she may have towards men, despite being a carnivore. Terumi's similar complex towards his mother, as well as his persistent nice guy personality, thaws her normal icy demeanor and she opens up more to him as a result.
** Hanada has a severe complex towards her breasts due to men ogling them during her childhood and adult years. It doesn't help when she can't go anywhere without guys staring at her lustfully. Thanks to Terumi, she's getting better and is taking more pride in herself.
** Rokujou's love for Terumi comes to a head when she tries to force him to marry her. Due to Kaoruko's intervention, she was made to realize that unless she changes her personality somewhat, eases up a bit on Terumi, and learns to love his new, more confident demeanor, she won't be able to get Terumi to love her.
** Semi's interaction with Terumi is breaking her self-imposed notion that "women are forced to stick with the guys they're going out with", even if the guy is a jerk. Kaoruko is hoping for this to succeed in order for Semi to "free" herself from the abusive boyfriend. Starting to become realized when Semi becomes more cheerful and is starting to fall for Terumi.
** Tsukasa, Terumi's fear of women personified, is going through this trope as well. Hiding her bitchy personality behind a facade of popularity, she hopes to be ''the'' most popular girl by going out with popular guys, even if the guy happens to be a teacher. When Terumi exposes this and shows her she's not as cool as she would like to believe, Tsukasa starts to grow feelings towards her victim, whether she wants to or not. Terumi is also the only person to see different sides to Tsukasa's personality besides calm, cool indifference, inferring that there is more to her than one would realize.
* CliffHanger: While the series is a weekly manga, only 8 pages are published per chapter, 9 or 10 if the audience is lucky, as the author has no assistants to help her. But almost every chapter ends with a cliffhanger on something Terumi will or will not do.
* CoitusEnsues: Occurs several times throughout the story, and sometimes without warning. Terumi and his target can be talking and then next page might show him and the target making out with each other.
* ADateWithRosiePalms: Happens quite often with most of the cast members when they're thinking about someone else; particularly, with the main character, Terumi.
* DemotedToExtra: Happens with each of the sex targets after their story arcs. Though they do occasionally return to contribute to the story or show what they are up to since their time with Terumi. Some even hinted at wanting to get back with Terumi: Asahi and Aoi.
* DistractedByTheSexy: A trope that is heavily used in this story. Every target introduced by Kaoruko have the potential to get every guy to stop what they're doing and stare at them. When she can, Tsukasa loves to abuse this trope. Kaoruko herself is the ''queen'' of this trope.
* DoomedByCanon: [[DiscussedTrope Discussed]]. Those who know the story of ''TheTaleOfGenji'' will know that [[{{Yandere}} Rokujou no Miyasudokoro]] goes on to [[spoiler: ''kill'' two of her rivals out of love for Genji]]. Terumi makes that very same connection when Kaoruko brings up her {{Expy}} as the third target, and his reluctance makes Kaoruko change the target to Hanachirusato's {{Expy}}. Time will tell if [[{{Expy}} Miya Rokujou]], the fourth target, will follow suit here; already showing {{Yandere}} tendencies down to a tee.
* {{Expy}}: By the nature of the series, most major characters are to a greater or lesser extent Expies of characters from TheTaleOfGenji. [[JustifiedTrope Justified]] because Kaoruko is intentionally putting women in Terumi's path whose circumstances resemble those of characters from the Tale, who she almost certainly sought out for this purpose.
* TheFaceless: Most men in this manga are like this since they only serve to be mindless idiots who can't help staring at sexy women. Professor Konoe provides some plot but he too is faceless.
* ForcefulKiss: Terumi is becoming a master of this. Whenever something is not going his way or he can't repress his urges anymore, expect his target to be on the receiving end.
* GilliganCut: While running on an exercise machine at the gym, Terumi was feeling angry with himself for masturbating to Kaoruko's naked body the other day. The coach, who's also one of the targets, tells him not to overwork himself, to which he replies he won't... Cue random guys commenting on how he suddenly collapsed and is in the infirmary.
* GreenEyedMonster: Similar to the OperationJealousy trope below where an outsider is seen glaring at the current couple.
* ImprobablyFemaleCast: Aside from the protagonist, Terumi, the only other prominent male character of the series so far is his recurring friend at the university and a teacher who has yet to actually show his face. Even Terumi's father, the plot-device that kicked him out of the house in the first place, hasn't been seen since the very first chapter.
* LuminescentBlush: Terumi is susceptible to this everytime he does something perverted or a girl says or does something to him that makes him feel happy. It's the same in reverse.
* MomentKiller: Often. Many of the chapter cliffhangers are "will Terumi finally make relationship progress and/or get laid?" and the answer in the following chapter is generally, "No." Usually because he loses control and goes too far, though sometimes other people or circumstances end up interrupting.
* {{Netorare}}: A trope that is played with in the story. Has not yet developed into the genre everyone knows it for, namely the audience and nice guy protagonist suffering in seeing their sweet girlfriend stolen away by an asshole, and giving into that asshole: mind, body and soul.
** Terumi's interaction with Semi is an inversion of this trope; Semi's boyfriend is the one implied to be cheating on her and Terumi is comforting Semi's state of mind in the jerk's place. This comes close to being more "Netori".
** Kaoruko notes how much she hates those type of men.
** Considering the original tale having Genji sleeping with married women, this makes it questionable about what will happen to Terumi in the story. Terumi himself does not want to invoke this for fear of inciting the guy's wrath. [[spoiler:This partially comes true when Terumi is shown shaking in fear when he thinks Semi's boyfriend is coming home. Thankfully this is not the case and admirably, Terumi was prepared to face the consequences for his actions.]]
* NotSoDifferent: Characters in the story to one another:
** Terumi and Asahi: Both are clueless when it comes to going on dates or having any sort of sexual experience.
** Terumi and Aoi: Both parties have [[spoiler:complexes towards a parent; Terumi for his mother, Aoi for her father]]. As a result, both parties just want to be accepted and held for who they are.
** Terumi and Hanada: Both were originally shy when dealing with members of the opposite sex. They both get better but they're still not completely over it.
** Terumi and Semi: Both want a relationship in which their respective partner pleases them both physically and emotionally. On a lighter note, both complain about having drunken neighbors knocking on their doors trying to get in.
** Terumi and Yuu: Both want to enter a relationship filled not only with sex but with actual love.
** Asahi and Aoi: Both meet each other and immediately think that they will not be able to get along due to their closeness with Terumi.
** Kaoruko and Tsukasa: Both are willing to use their bodies and charm to seduce and manipulate guys to do what they want.
** Terumi and Tsukasa: Both are somewhat twisted human beings who want to get into the pants of the opposite sex, regardless of circumstance. They even gave each other a ForcefulKiss at certain points of the story. Finally both had a [[TeacherStudentRomance kinky relationship with an authority figure.]]
** Terumi and Tsukiko: Both are perverts deep down and lets their imagination run away with them at times.
* OnlySixFaces: Aoi looks a ''lot'' like Kaoruko with a haircut. Otherwise, most of the women in the series and Terumi have very similar rounded heads/faces.
** Also, Rokujou no Miyasudokoro's yandere face resembles Tsukasa’s face.
* OperationJealousy: A continuing theme to get someone to feel jealous of a current couple; particularly, anyone currently with Terumi.
* PoolScene: After workout, both Yuu and Kaoruko relax by the pool. Starts becoming hotter when [[spoiler: Kaoruko offers to kiss Yuu. At that point, both are completely alone and have the pool all to themselves. Unfortunately it goes nowhere.]]
* SettingUpdate: Invoked, kind-of. The whole plot is kick-started when Kaoruko decides to use Terumi as a guinea pig in her plan to recreate the circumstances of TheTaleOfGenji for her research.
* SexIsInteresting: One of the major important plot elements that makes this story so enticing. Seeing Terumi grow as a character and him having to do fourteen different women of different ages, personality and background makes for an interesting manga.
* ShoutOut: [[spoiler:After getting Terumi out of Rokujou's house]], she advises her nephew to continue maintaining his teacher-student relationship with her... [[http://www.batoto.net/read/_/221514/minamoto-kun-monogatari_ch112_by_vortex-scans/8 all while re-enacting the infamous]] "[[Manga/FutureDiary Yandere Trance]]" pose.
* SpitTrailKiss: A trope often seen in this manga; many of the women and Terumi love doing this to their respective partner.
* TheTease: Many attractive women in this manga love invoking this trope, especially to our main protagonist.
* WhamEpisode: Chapter 111 reveals that [[spoiler:Kaoruko had told Rokujou about the conquest even before she met Terumi again. Not only that, she seemingly sabotages Terumi's efforts in keeping Rokujou's yandere side dormant, blatantly telling her that Terumi doesn't love her]]. With that, her research has taken a grimmer turn to it.
** The following chapter softens the impact as Kaoruko explains her actions. Things could've taken a turn for the worse had she not interfered.
