Plus gonna have a lot of wrongs point byul point that hyesung abandoned him for a time when he was born hyesung discovering that dojin hide this from him this family gonna go through a rough path poor Luna
What I'm thinking is it's gonna have Hyesung actually kick out byul and dojin since dojin did just punish byul for "lying" to him when dojin been in contact with the mother the whole time.
Hyesungs probably gonna call dojin a hypocrite ect and byuls probably gonna defend the grandma in which I'm thinking Hyesung being rightfully angry will say something like if she's so amazing why don't I do the same and "abandon" his son and husband (kick them out, or storm out himself). They'll probably make up soon but yeah.
Omg they gonna fight ;_; and it's gonna be ugly, it's gonna have a lot of cries, cold treatment, and someone gonna run away and it will be byul he will to siwoo house
