Koharubi finished this recently, just saw the last ep.
Great show. Last episode resolved nothing, in terms of main pairing(not that there's much to resolve, really), so there's hope for a second season - but frankly I don't think it's needed. It's a slice of life show, and it just ends, while the characters' life still goes on - I think that's pretty nice in itself.
Of course, there's absolutely great secondary pairing of the president and Oumi - which more or less got resolved, even if in the end
she decided not to kiss him. Guess she just can't help teasing him...or maybe she was afraid of causing a heart attack before his exams

All in all a very enjoyable show, I'd recommend it to pretty much everyone.
