Anyways she goes to the wedding and see a guy crying. and she asks him whats wrong and she finds out that he's related to the bride and that he is in love w/ her or something like that. well one of them says something that she doesn't like she gets mad. moves out of her house and move into a boys dorm, there is another guy who lives in the dorms but i don't remember much about him. But in the end of the manga boy one and boy two have a swim race. boy one can't swim so she jumps in to help him and in the end she ends up with boy one. well thats all i really remember about this manga so if you can help me figure it out then thankx alot.

The only manga that comes to mind is the manhwa 'Jack Frost'. I know you'll like it. It's Ongoing, Original, and a Horror.
