Acting all his struggles and his past like a joke. His whole childhood was ruined but he still came back for a baby he didn't asked for and that baby was ungrateful to him and all he did was "sorry". He didn't even try to understand hyesung's past. Byul is too used to luxury and pampering from his parents that he doesn't know what's the feeling what hyesung suffer and yes I said what I said he's a spoiled brat now. He's even thinking of letting hyesung meet with that grandma like ugh I'm disappointed.
And that kiss is a mess. A family matter turned into shit teenage cringe moment. Nobody kiss someone to make them stop crying he's an alpha stop treating like he's 5 years old
