I don't agree with any of the comments above me at all. Dude's boyfriend KILLED HIMSELF!!! He has reasons for feeling the way he does. Ue is NOT the "second option" that is just plain bullshit, we know Mafuyu genuinely loves Ue back. He just can't help but remember all his trauma about Yuki, (which btw he blames himself for) and is having a hard time expressing his feelings. Saying you don't like Mafuyu bc "Ue deserves better" is just plain apathetic. Read their story bros, feel some empathy for the poorguy.
