Hmmm I think he gets rejected or runs away because in koi ni Nare he is living at a dorm.... so maybe he can get away from his brother or something...oh but than he goes on a date in koi ni nare too...or so it seems (maybe meeting his bro)i think he will definitely be rejected after confessing though but they'll prolly end up together (&breathes)
Have faith, the genre says romance but not tragedy.... I think that it's going to end well, here is the raw of ch.2. I think that the story is going to happen in a longer lapse of time, now he is in middle school and in Koi ni Nare he graduated from High School and he's going to university, maybe he's gonna meet someone new or the relationship with his brother goes to a next step. Be positive pleeeeeease, he deserves happiness because he's a generous and cheerful guy....

I wonder if his brother and a boyfriend are the gay "friends" that nakajima mentions in Koi ni nare?
I don't see this manga ending happily since they're obviously not together in koi ni nare... I have a sinking suspicion that the older brother dies or something before nakajima can come to terms with his feelings and confess. I don't know why I think that, I just feel a tragic vibe coming from this one. I hope I'm wrong....
