I really like this but the sisters were pretty goddamn annoying. Especially the parts where they were like "boys are all stupid" meanwhile they were the ones who kept getting in the way with their stupid advice. Mind you I still love this and think its the author's best work, but I would've preferred if they didn't spend a good portion of each chapter on the sisters and instead on the more adorable main couple.

I remember that it was full color, no more than 50 chapters, pretty sure it shounen ai, and generally a non stressful one. I remember specifically that there was some rich high school rival who came in around the last 10 chapters who kidnapped the bottom only for it to turn out that he was incompetent and the bottom just sort of walked out on his own because the light security. And then everyone around was saying how pathetic and petty he was. I remember it was surprisingly refreshing because it felt that it was going down the route of an overdramatic finale just for it to fizzle out.

It feels weird to have sex scenes at the end of a very pure and innocent story like this. Because we also saw them when they were younger and it feels weird to see them having sex after seeing their young selves
