Maybe becauase he has a really big ego(〜￣△￣)〜
Personality dear. You can see clearly that he's far from the type to just flat out confess his love.
that's what we call "tsunder" hhhhhhhh!!!
i should say violent tsunder seme hhhhhhhh!!!
I think the seme is just realising he loves him he just needs to sort his head out
If he's in love why not just confess???
No need to hurt the other one
