Seeing the person you love almost getting killed by his family is also not nice. His brother almost did attempted murder, you know? You can't blame immaturity for that.
Minyoung did his very best to not kill them all, you see.. so maybe he just chose the quickest way which is telling cheol's family that he's in love with a 'homo bastard'

I'm on minyoung side, if I were him I would do the same thing he did, or I might even do something worst just to remove the things that's causing pain on someone I love, but this is so fucking painful seeing cheol's past
