The story follows seven college students entangled in a complicated and sometimes painful web of relationships and desires. Much of its plot is driven by the main characters' exploration of their relationships and sexuality, as well as finding out what exactly motivates each of them to behave in the way they do.
The manga contains examples of following tropes:
- Beta Couple: The usual use of this trope in yuri genre is subverted by Asuna and Fueko, who start off as a reasonably well-adjusted lesbian couple serving as foils for the yet-to-get-together Ruki and Sachi, but whose relationship gradually falls apart concurrently with the main couple's one growing stronger.
- Bittersweet Ending: Sachi and Ruki stay together after graduation, and Maasa, Meru, and Remi end up in a weird semi-professional, semi-romantic triangle, but Asuna and Fueko never seem to get back together or move on with their lives.
- Can't Have Sex, Ever: Downplayed. Asuna and Fueko can have sex, and did so several times in the past, but Fueko is asexual and sees it as a heavy burden, while Asuna can never get enough of it. Neither of them is selfish enough to demand from the other to change her ways, so they voluntarily limit their physical interactions to much tamer expressions of affection.
- Distant Finale: The main bulk of the manga occurs in the girls' first year in the university. The epilogue takes place around the time their graduation.
- Drama Bomb/Gut Punch: Fueko breaking up with Asuna. They seemed like a reasonably well-adjusted Beta Couple until then—not without their issues, but nothing that couldn't be worked out... and then they break up, and never get together again, despite still loving each other. It is the exact moment when you realize that not everyone will get a happy ending in this manga—and it makes you root for them even more.
- Dysfunction Junction: So, let's see, we have a girl in denial of her feelings for a female friend, said friend who is on the verge of snapping over her dysfunctional relationship with her boyfriend, a girl who suffers from an unspecified narcoleptic disorder to nearly life-threatening levels, a lesbian skirt-chaser with a drinking problem, a sex-obsessed nymphomaniac, a former bulimiac with a penchant for getting into trouble, and a girl forced (and failing) to live up to her rich family's expectations. This can only end well.
- Ensemble Cast: While Ruki and Sachi spend the most time in the limelight, other girls all get arcs of their own.
- The First Cut Is the Deepest: Downplayed. After getting together with Sachi, Ruki recognizes how traumatic Sachi's previous relationship has been and resolves not to be like her ex-boyfriend in any way, which, at times, hinders their new relationship. Luckily, they manage to work it out.
- Good Bad Girl: Remi is the most obvious example, but really, all of the main girls (except maybe Ruki) have very loose morals, but none of them is actively malicious, and they look out for each other in need.
- Hidden Depths: All of the main cast have them—even the ones you'd never suspect.
- Incompatible Orientation: Ruki believes this to be the case with her and Sachi, who appears to be straight but turns out to be bisexual. A much more dramatic (and unusual) case is that of Fueko and Asuna—a perfectly asexual person and a hypersexual nymphomaniac, respectively.
- The Mourning After: It is strongly implied that neither Asuna, nor Fueko ever fully recover from their breakup—and never fall in love with anyone again.
- Please Dump Me: Fueko tries to pull this on Asuna, but it doesn't work. So she breaks up with her directly.
- Rewatch Bonus: Many off-handed remarks made by characters in the early chapters become a lot more meaningful (and, at times, harsher) after the later chapters' revelations of what really drives them to do and say such things.
- Seven Deadly Sins: Word of God reveals that the Ensemble Cast got started as Embodiments of Vice: Ruki embodies Pride, Sachi is Wrath, Fueko is Sloth, Asuna is Lust, Maasa is Greed, Remi is Envy, and Meru is Gluttony.
- Star-Crossed Lovers: Asuna and Fueko. It is painfully obvious that they love each other (in the agape kind of way), but Fueko believes they shouldn't be together because she cannot give Asuna what she wants (lots and lots of sex), while Asuna loves Fueko too much to force herself on her. In the end, they never get together again—and never enter another relationship with anyone.
- Tomboy and Girly Girl: The boyish Ruki and the proper lady Sachi, respectively. In a subversion, Sachi ends up wearing the proverbial pants in their relationship in a long term.
- Yuri Genre: It's a manga that focuses mainly on lesbian relationships.
