Base Breaker: Several women in the story are either a woman that a fan will love or hate:
Arguably, Chisato Hanada is this. She's nice, she cooks, and is even willing to put up with everything the male says. The perfect woman, right? Not to some fans. As a result of this, some say that she's completely boring; making women, as a whole, look submissive and weak. What's more, many readers have interpreted her relationship with Terumi as taking her first steps in becoming a slut.
Several readers denounce Chuujou Tsukasa as an unlikeable slut due to torturing poor Terumi into having his current phobia and for sleeping with any guy she thinks is popular. However, she also has similar qualities to Terumi and arguably her mere presence moves the story along in an interesting manner. Tsukasa herself has many sides to her personality, making many of her fans looking forward to whenever she shows up again.
Ensemble Darkhorse: Some women Terumi meets in the story have a lot of popularity going for them, despite only being background characters. However, Tsukiko is a major one. She isn't considered a target (at least not to the reader's knowledge anyway) but her endearing personality, her love of the Genji story, the fact that she will support her friends in any way possible and that she's best friends with Asahi makes her a very strong character. It helps too that she's very attractive and has a very cute little sister.
Fan-Preferred Couple: Seeing as how this is a series where the main character gets it on with a large variety of women, there are sure to be MANY of these.
Terumi and Hanada was seen as such a lovely Moe couple to some readers that people wanted Terumi to just ditch the whole Tale of Genji experiment for her.
Terumi and Tsukasa is also popular amongst readers; thinking that it's poetic irony that the girl who previously bullied Terumi ends up falling head-over-heels for him.
Terumi and Tsukiko is another good one as well, since they are able to talk with each other like closest friends and share the same perverted viewpoints.
Launcher of a Thousand Ships: Unsurprisingly, Terumi Minamoto is this. Not only is he set to have new ships with up to 14 different women for his Tale of Genji objective, he is also shipped with people who aren't even established targets.
Les Yay: Rokujou gives this impression to Tsukiko, Asahi and other girls at the university due to hailing from an all girls university. It would actually start making sense as to why she's so interested in Terumi in the first place...
Kaoruko offers the opportunity for a steamy kiss to ensue between herself and Yuu. It almost happens...then Yuu vehemently puts a stop to it, saying that they're both women and can't be doing that sort of thing. Cue the collective groan of the audience.
FINALLY occurs in Chapter 163 when Rokujou makes out with Yuu, making this the first time a kiss between woman is shown on-screen.
Happens again in Chapter 166 when Rokujou forcefully makes out with Kaoruko.
Magnificent Bitch: If only we knew Kaoruko's motivations for recreating The Tale of Genji in real life...
Later chapters show that Rokujou fits into this trope as well, since she'll do whatever it takes to get Terumi...
The thought of Terumi doing something remotely sexual with Kowaka Shian, who is 10 years old, is going to raise a few eyebrows. Viewers will have to trust in what Kaoruko is doing.
Wham Episode: Chapter 180. Terumi finally meets up with his girlfriend Yuu after the beauty pageant...and finds out she's being transferred to Osaka.
Will They or Won't They?: Watching Terumi feel more and more comfortable around Kaoruko, and Kaoruko showing she cares for him after all, even if only for the sake of her research, does seem to imply they are slowly heading towards giving into incest for real.
