I would prefer that he gets with Segawa, and leave the other 2 in a brotherly relationship, nothing more.
And that he sends his father to fuck off, because the shitty old man has not deigned to have a meeting with his own son and denies his eldest son, in my opinion he is worthless as a father, and don't forget the mother, we don't even know his mother, who apparently is not interested in his own son considering that they have already been in manga time for about a year.
hopefully the message gets across, english is not my native language, so sorry if is misconstrue, I would appreciate feedback
