Not hating on him though, hes young and very likely doesn't have full understanding of the situation. The only one I hate is grandma still causing trouble after all these years.
And if this ends with her being welcomed into the family im going to scream because she never ONCE properly apologized.
I doubt his parents will ever tell him the circumstances of the pregnancy though. So Byul only has a small part of that story he overheard.
In a perfect world Dojin would sit Byul down and tell him the things he made Hyesung go through to put things into perspective but the author loves rug sweeping so yeah it'll never happen. Hyesung will tank this and be made to forgive his mother in the end 100%
I really hope he doesn't forgive his mother.
Sorry Byul but being forced into pregnancy vs choosing to have a kid and then leaving them with their abusive father so you can restart your life baggage free is NOT the same thing. I hate how this went down but i expected it.
