Let's be honest, we all know how this is going to go. Hyesung is going to be guilt tripped by Byul into forgiving his mother just because she's a good grandma to him. If the author truly wanted to respect Hyesung in his decision regarding his mother, she would of never been included in this story.
You just gotta accept that this author is shit at not making Hyesung seem irrational, grown up or get respected by anyone in his family.
