I think Byul did something when they were kids that he is not aware of that he already hurt Siwoo maybe about kissing or something that is big deal for Siwoo but not for Byul ╮( ̄▽ ̄)╭

But it is a big deal for him because he was brainwashed into thinking only adults are allowed to do that but he’s still a kid so he shouldn’t do that yet. Kissing is a big deal to him at least that’s how I’m viewing it. Byul just doesn’t like that people aren’t respecting his own boundaries. If he’s not comfortable kissing and says that why does he owe someone. It sounds like a lot of his relationships were genuine teenage interested and then lost interest types too.
Forgive dead Tony - I cursed you out deserving to die because thought you cheated intentionally. My bad!
could you give me spoilers?
