Urashima Keitaro is a failure. He's been trying to get into Tokyo U, for which there is no american comparrison. Getting into harvard is a cakewalk by comparrison if that gives you any idea. He's been trying for three years but his grades chomp and he repeatedly failes the entrace exam. So why is he putting himself through this? He has this memory of when he was a kid when he was playing with this girl and he remembers that they made a promise to one another that one day they would meet at Tokyo U and be happy. So ever since he's been shooting for this one goal because of a promise made when he was probaly 4 years old or something.
He becomes the manager of a girls dormatory (which was previously a hot spring owned by his grandmother) where he meets Narusegawa Naru, someone who's also trying to get into Tokyo U. He thinks that she might be the girl from his memory and of course there are all sorts of whacky little adventures but what the core of it is, is that their relationship is completely dysfunctional. She's constantly beating the snot out of him and thinks he's a pervert and he's always placed into these awkward situations.
So what's dysfunctional you might ask? I find it adorable. It's so sweet it almost makes me want to choke when I think about it. I find myself thinking things like 'if only...' and gads, even I know that's ridiculous. I've aparently never managed to emotionally mature pass the stage where you run around pulling the hair of girls you like and this whole insane and juvenile crap. In all of these stories that I find to be perfect romances from books I've read and whatnot, it's always founded in conflict. In characters who end up bickering with one another, neither able to admit their feelings and instead channeling that energy into irking the hell out of whoever they like. I swear to God I'm a fucking eight year old.
