I was introduced to this manga because of its new adaptation. In brief, it is a truly great love story that is romantic, suspenseful, and very erotic, with no competing love interests. The story progresses linearly from the alternating viewpoints of the two main characters.
The first high school arc introduces the main couple and their unusual relationship, where one rents the other. This arc culminates in a dramatic "decision time" climax at chapter 118, establishing a new baseline of support for their continued relationship as roommates in college, though the romantic element remains unresolved. You could stop reading here if you don’t like it, but I imagine you will keep going because the story has great pacing, and the main characters are well-developed and sympathetic in their own ways. You will find yourself cheering for them!
Although the renting aspect fades away, the theme of "exchanging" reappears as a rationale for why one character might do something for the other, in the absence of explicitly saying, "Because I love you, you are my girlfriend." These are not perfect Mary Sue types; each has a history of abandonment or rejection, and you can really feel their emotional struggles as they deal with jealousy, insecurity, and possessiveness. There are a couple of points where the machine-translated (MTL) version falls short and may make you want to shake the characters for acting like stereotypical useless lesbians in denial. Just push through these parts, and you’ll quickly return to enjoying the story. I strongly recommend the Amawashi translation up to its latest update, as it is far superior to the MTL.
While the satisfying slow-burn romance plateaus somewhat when the main couple starts living together, the more slice-of-life feel is still very enjoyable. Although the main couple still has a long way to go in admitting and expressing their true feelings to themselves and each other, there is plenty of "dating" and a lot of sweet emotional intimacy that will give you those "Yuri is Life <3" good vibes. Their reluctance to risk what they have in hopes of something more adds to the tension.
However, don’t worry—giving them a bit of a push, along with some nice comedic and dramatic tension, comes from how the main couple deals with the "secretly deeper" nature of their relationship within their small friend groups. Even if they don’t admit their romantic relationship to themselves, the main couple recognizes that some of their actions might seem beyond normal roommate behavior (especially the kissing and sex), and they increasingly have to handle friends’ skeptical or enthusiastic questions and antics, such as, "Where’d you get that hickey on your neck?" The friends are nicely integrated into the story but don’t have their own subplots or relationships; they are there to further develop the main couple’s relationship, which works perfectly for me. The story is still ongoing, so that’s my review for now! 10/10 for me.
