Naoya Mukai is the happiest man on earth. After many many confessions, his childhood friend Saki Saki has finally accepted and become his girlfriend. All is looking well for the young man, and after proclaiming his love for Saki, he goes to wait for her to finish club activities on the roof, but upon arrival he is suddenly confessed to by Nagisa Minase, an extremely cute girl with a heart filled with love. How can Naoya possibly say no? Distraught that he would have to reject Nagisa, Naoya comes up with a brilliant one of a kind plan - he'll simply two-time Saki, with her permission of course. Thus begins the tumultuous love life of three young idiots.

Girlfriend, Girlfriend (or Kanojo Mo Kanojo in Japanese) is a currently ongoing Rom Com manga created by Hiroyuki (Aho Girl, The Comic Artist and His Assistants, Doujin Work). It began serialization in Weekly Shonen Magazine in March of 2020. In July of 2021 an Anime Adaptation began airing produced by Tezuka Productions.


This manga contains examples of:

  • *Bleep*-dammit!: In a series where sexual references are abundant, it doesn't take much effort to understand that Naoya is saying "threesome" (with the "some" part blocked out by the sound of steam from a boiling kettle) when he announces his intent to abstain from getting into one with Saki and Nagisa.
  • A-Cup Angst: Saki and Shino are both on the small size and is a constant source for angst, especially when they compare themselves to the much more endowed Nagisa and Rika
  • Ambiguously Bi: Both Saki and Nagisa to varying levels. While small, Nagisa had no objection when Naoya revealed he was having threesome fantasies, even revealing she figured that would be a possibility. For Saki though, her relationship with Naoya is pretty much the only thing that keeps her from being considered gay. She freaked out at the cuteness of Nagisa, lamenting that she wasn't dating her, drools over Rika and her sister, and her friendship with Shino is often more romantic in nature then Saki's time with Naoya.

  • Bland-Name Product: Rika makes videos for "MeTube".
  • Brutal Honesty: A major aspect of Naoya's character is that he always tells the truth about how he is feeling. Even when he knows it will make the girls angry at him, he tells the truth. And if it's something that can make them sad or worried, he will tell the truth and immediately look for a way to fix that issue, no matter how insane his solution sounds.
  • Buxom Is Better: Part of Rika's popularity of MeTube is her large chest and how her videos serve to emphasize it.
  • Casual Kink: Parodied. Saki starts to panic that she might have an NTR fetish after finding herself incredibly turned on when watching Naoya and Nagisa having an intimate hug.
  • Chastity Couple: Even though Saki is pretty obsessed with stuff about sex, it's revealed that Saki and Naoya haven't so much as kissed since getting together. This even becomes a plot point later as Shino tries to set things up so that Saki and Naoya can have a special first kiss. The fact that despite every opportunity given and Saki still didn't kiss Naoya starts to give Shino doubts that Saki truly loves Naoya.
  • Childhood Friend Romance: Naoya and Saki have known each other since they were little kids, and have apparently had feelings for one another for years.
  • Clingy Jealous Girl:
    • Saki's the most prominent example, being hyper-vigilant to any sign that Naoya could be falling for another girl. Justified with the fact that Naoya is openly two-timing her with Nagisa. Natural, she's worried that he's going to either leave her in favor for someone else, or decide he wants to add another girl into the mix.
    • Nagisa comes off as a more downplayed variation of this trope. She has admitted on a couple of occasions that she'd have preferred to have Naoya to herself, but she's pretty respectful of the fact that Saki was Naoya's girlfriend before she was, and ultimately does her best not to come between them in any way. On the other hand, she plays this trope absolutely straight when it comes to Rika, to the point where she openly freaks out upon learning that Rika had been visiting Naoya at his job without any other customers around.
    • Though Rika initially offers to be Naoya's third girlfriend, she eventually does a 180 and tells Naoya that three-timing won't be tolerated, and that he'll have to break up with his current girlfriends if he ever decides to get with her.
    • Shino sees Saki as being far too lenient, and claims that she'd never give Naoya the opportunity to fall in love with another girl if she were the one dating him. Of course, these attitudes are pretty much the standard among those who participate in monogamous relationships, and one could make the case that these aren't necessarily signs that one is overtly clingy or possessive.
  • Covert Pervert: Although Saki desperately tries to appear otherwise, it is clear that Saki is a massive pervert. From openly lusting after Nagisa to secretly searching up ways to initiate sex with Naoya. Notably, when Naoya abstains from having any sex with his girlfriends, Saki is very obviously disappointed by this, which even Naoya himself notices.
  • Deconstructive Parody: Naoya's harem situation may seem like a dream come true, but there are multiple instances where it's made clear that the girls are either putting up with the harem for the time being or are outright bothered by it. Both Saki and Nagisa don't like the idea of sharing their "firsts" with the other girl, such as with kisses or dating, and Saki especially feels left out at times and is always shown resenting the fact that Naoya openly two-timed her. At the same time, Naoya is determined to make both girls happy even with all those difficulties. It's just that his methods to achieve that tend to make a mockery of a little thing called "common sense". And above that, every person who eventually learns about the poly relationship never think of Naoya as lucky or the girls as sweet—they think everyone involved is an idiot, Naoya for two timing, the girls for letting him, and any hopefuls idiots for falling for a known two-timer.
  • The Determinator: Pretty much everyone on one level or another.
    • The biggest is of course Naoya, when he gets it in his mind to do something, nothing in this world will stop him until he accomplishes his goal. The downside is that he is like this with pretty much everything and can be a bit tiring to deal with. Though Shino and Nagisa both end up falling for him because of his steadfast determination, Saki just finds it annoying most of the time.
    • Nagisa when it came to getting herself prepared to confess to Naoya trained her body and spirit in a Training from Hell type regiment while also teaching herself how to be a 5 star chief. Though the downside of this was she neglected school for several months and as such is a complete idiot when it comes to school work.
    • Marika almost rivals Naoya when it comes to being undeterredly focused on a single goal. Nothing will stop her, even if she has to learn from scratch a new set of skills, or debase herself, there is nothing that will stop her.
    • Saki is actually usually more of an Extreme Doormat, at least when compared to the obsessive determination of the the others, but it's shown in the past she can be just as determined as Naoya when it comes to something she wants. In the past it was becoming friends with Shino, and no matter how much Shino said no, Saki was not going to be deterred.
  • Disproportionate Retribution: Saki slugs Naoya across the face for suggesting that he be able to date her and Nagisa both at the same time.
  • "Double, Double" Title: The English title Girlfriend, Girlfriend.
  • Dull Eyes of Unhappiness: Both Saki and Nagisa have this look shortly after Rika forcefully kisses Naoya.
  • Friendly Rivalry: Nagisa and Saki, despite being technically love rivals, are for the most part quite friendly with each other.
  • Hot Springs Episode: An arc of the series focuses on everyone going to a hot springs; it serves to be important in helping Nagisa deal with her insecurities and for Shino becoming more entangled with the central trio.
  • Hypocritical Humor: When the three are sleeping on futons together, Saki believes Nagisa is a pervert trying to have sex with Naoya when she really isn't. Ironically, as Nagisa realizes after searching through Saki's phone, it is Saki herself who is the pervert interested in having sex with Naoya.
  • Insane Troll Logic: The basic premise of the series, really; Naoya thinks the best option for his relationship woes is to just date both girls at the same time. His first and often only solution to any problem is to go straight to the most extreme option possible. Saki isn't entirely convinced his plans will work out, but Naoya is nonetheless determined to prove otherwise.
  • Insecure Love Interest: Both Saki and Nagisa fear that for one reason or another Naoya will at some point decide to be exclusive again but with the other girl. They get better as the story goes on, but neither one completely trusts Naoya, especially with other girls, something Rika actually calls them out on.
  • Love Triangle: The series begins with the forming of one between Naoya, Saki, and Nagisa after Nagisa confesses to Naoya, but Naoya reveals he is already dating Saki. Not wanting to reject such a cute wholesome girl, Naoya decides to ask Saki if he can date both girls, it takes a bit of convincing but eventually Saki agrees to the relationship. Later in the series with the addition of Stalker with a Crush Rika and the secretly pining Shino it becomes a Love Pentagon.
  • Meet the In-Laws: Naoya's mother and father finally come home after being away from their house for so long, allowing them to come face to face with the two timing relationship and the extra girls staying in their home. Predictably, they're both angry with the relationship...but the father is simply jealous of the situation, while the mother points out that it can't last forever on empty promises and the girls' good will. Ultimately they're okay with him dating Saki and Nagisa, but they haven't even considered Mirika and Shino as official girlfriends (yet).
  • "Open!" Says Me: Naoya punches a padlock locking a gym storage room in an attempt to open it, but it predictably fails and bloodies his fist instead.
  • Pilot: The original two-chapter manga pretty much has the same plot as the first chapter, but with Naoya's mother finding out about their circumstances early and charging Naoya for letting his girlfriends live in his house.
  • Repetitive Name: Saki Saki, her parents thought it would be cute if her given name was the same as her family name.
  • Shipper with an Agenda: The reason Shino wants Saki and Naoya to be together is because she is in love with Naoya herself, and she won't be able to give up if there is even a small chance Naoya could accept her.
  • Sound-Effect Bleep: In the anime, Naoya saying "threesome" is blocked out by the sound of steam from a boiling kettle.
    Naoya: I'll give up on a three***.
  • Spiritual Antithesis: To a manga that started getting serialized right alongside it, The 100 Girlfriends Who Really, Really, Really, Really, Really Love You. Both are wacky gag-based harem romantic comedy manga, both have devoted and straightforward male leads, both have everyone admit that what they're doing would be considered cheating in any other relationship, and both have the girls try to make the relationship work as the harem grows. However, there are key differences; while the attraction is supernatural in 100 Kanojo, everyone is genuinely in love and they are willing to make friends with the rest of the harem, eventually piling up into a family dynamic. Rentarou also has energy to spare so his girlfriends never have to feel like they're left out of the loop. In contrast, Kanojo Mo Kanojo has the love happen naturally, but it focuses on the problems with a harem; that the girlfriends he has do in fact want to monopolize their man's attention even if they like the other girls, and explores what happens if a haremette wants him all to herself or when he can't keep up with their needs and his own selfishness. The harem is also much smaller and he only intends on dating two of them.
  • Stalker with a Crush: Rika at first was just mildly interested in Naoya for the fact he was in a threesome relationship, but she quickly fell head over heels for him. Unfortunately Naoya soundly rejected her, but Rika isn't one to take no for an answer.
  • Stupid Sexy Flanders: Saki is very afraid that Naoya might find Nagisa to be more attractive than her. One of the main reasons behind that fear is that Nagisa is so cute, even Saki feels attracted, so how can Naoya not be?
    Saki: She gives me weird feelings, even as a woman!
  • Victoria's Secret Compartment: Rika hides the key to the handcuffs she has locked both herself and Naoya in down her chest. It doesn't stop him from reaching in and grabbing it.
  • Yamato Nadeshiko: Nagisa worked on her mindfulness and cooking skills for three months, so she can make herself presentable as wife material to Naoya.
