... The only way I could think of for him and Enomoto to get togehter now is if Enomoto's hometown love interest breaks things off with her somehow, whether it's because he can't really do a long-distance relationship, he was confused about the nature of his feelings, or turns out to be a two-timing double-faced bastard who has been cheating on her with another girl all along.
OH NOOOOOOOOOOOOOOOOOOOOO. Poor Motoyama-kun. He deserves for being a great wingman! I don't want him to get hurt by this, so I think he should just confess his feelings for both of them to move on from their relationship/friendship.
