Unripened Expression
This is something straight out of a dating sim game -- the main character is surrounded by 4 potential love interests: the tall and handsome childhood friend and his first love, the friendly vice class rep who is a fierce fighter, the happy-go-lucky mood-maker friend, and the lone wolf who has been very supportive of him (a tsundere?). Who will he choose? My predictions are either the childhood friend or the lone wolf, because the other two characters are too one-dimensional to be the one he will end up with.

These two are childhood friends and their parents are friends, they are not brothers, they are not half-brothers, they are not step-brothers! There's no incest involved whatsoever! That aside, so far the story seems pretty cute and sweet, though there seems to be unrequited love, it may not be unrequited after all...must read more to make a better judgement.
