I like how this story is actually digging into the negative psychological effects of heterosocialization. It's something my sister suffered from when she was growing up. She's ace/aro and grew up surrounded by media and friends and teachers and parents who would tell her to get a boyfriend, that being happy is to be in a relationship. So she fabricated feelings for people she felt nothing for, thinking that that's just how everyone is. It wasn't until high school when she started thinking she was broken, that something was wrong with her because she wasn't able to do what everyone else was doing so successfully around her. Once she found out about asexuality, her entire life made sense.
It's a common yuri trope to have the "I like guys [heart beats near female friend]" which is imposter syndrome. But many of these stories just treat it as a narrative trope rather than an exploration of a serious psychological issue. What I really like about this story is that it does that exploration. It's showing the MC's anxiety, her feeling of brokenness and being unable to fulfill what society expects of her. She directly references media she consumes and how her friends constantly tell her to get a boyfriend. The last page of the chapter is when she finally feels "normal," feeling what everyone else has been telling her she'd feel for men.
I tried dating a guy once in college. He was really sweet, very fun to talk to, intelligent, good-looking, a solid career in the sciences, called me "a beautiful person," made me breakfast in bed, but I could not see myself with him. I'd distract myself during more intimate conversations, thinking about lesbian fanfiction with my back turned to him. I'd start to aggressively think about women whenever he started talking romantic. That moment in this manga when MC felt sick imagining a life with the man she was with, I really related to her. I know that feeling so well.
Tl;dr, this story is really important. It's doing something I don't often see with this trope that I think is important to talk about. Heteronormativity makes queer people feel inadequate, broken, insecure. And this manga's such an excellent portrayal of that experience.
