I want HatoxChief...
... but you're probably going to get your wish. This is a Morishima manga, after all, and there's that thing about her: she likes stories about couples of girls falling in love, breaking up, then reuniting years later when they realize they still love each other. Their affairs with other partners, in the meanwhile, work just as stepping stones in the way to their happy end together. So, yeah... sigh... everything is pointing towards ChisaxChief. :/
