I was following updates for this manga for years until they finished on Batoto, and to be honest I'm not sure how I managed to keep pushing through instead of just dropping it from frustration. It has its good moments of course, but the guy tends to be really demeaning and selfish. Sure, it's the classic cold, intelligent yet secretly sincere boyfriend, but that's usually a really tricky balancing act that unfortunately, this series doesn't always pull off. Instead he just comes off as ungrateful and a dick, and since he can't communicate like a mature person he supposedly is, there's lots of unnecessary drama. Hopefully you like that sort of thing.
As for the MC, she's your typical dumb but good-hearted girl who makes stupid decisions and stays with the guy because she understands him. A lot of times I just kinda feel sorry for her.
The best thing about this is the ending; the MC actually finds a goal to pursue that's cool and unique, which was unexpected. Usually they just get married or become a teacher or something without much thought because that's the default for Shoujo manga, so it was refreshing to be able to see her as a more realistic character.
