Anime covers them faithfully? I read somewhere that manga and anime branch at some point.
If they don't, I'll probably start reading manga again, but I'm not trilled then. I was really take aback by conclusion, that Haruka has no idea what love is and that she and Yuu don't even consider what they are doing dating. Entire scene with Mitsuki's confession was so painful to watch. No matter how dense you are, If you are in high school, you has to know at least that if you are kissing and doing stuff with your "best friend" that means that you love each other and are dating. I just couldn't believe she was so naive (stupid). So basically, because they wanted to be special to one another, they became sex friends? I just couldn't look at their relationship in serious manner anymore and that turned me off to entire series. I understand it's 4-koma and Haruka's failing to notice that Misuki is serious for a joke was something I should expect, but there were way better ways to do that. That is my problem. Was it joke? Was it serious scene? Because either way, I couldn't stand it.
The anime is very close to the chapters it covers.
Haruka is kind of an idiot, but further chapter in the manga do show that while the two are a bit naïve in their feelings they do understand that they are not a normal relationship. Yuu also outright comes to the conclusion that she is in love with Haruka, but keeps it to herself.
All in all, it seems the two are still in the exploring phase of their relationship. Though the cynical thought is that the two are in the infamous S-relationship
Still it's a cute manga/anime that I don't think is meant to be heavily analyzed.
