She left her son with an abusive person when he was five and just moved on with her life... got married again made a new family and never checked up on him again until he hit the news...and then she got mad and blamed him for never trying to reach out for her.. you call that a mother?
If you were abused would you be okay with your closest people, your family, the people you trust the most in the world, meeting them as usual? Supporting them financially? Updating them and talking about you? All that behind your back..
Respect? Where is the respect towards Hyesung? Sure, Byul doesn't know what happened, but he is 17 yo and he is been meeting her for years now and he knows something happened, but he never bothered asking what... Dojin is even worse, he knows everything and exactly how it effected Hyesung and he still does this.
As an immature thirteen years old (according to you), who knows how it feels.... its make you lose all hope and want to ... its not about controling peoples choices its about trusting them to not to betray you... and no matter how you look at this, thats what they did...
Im kind of baffled how people dont respect byul's choice to see his grandma. Yeah the mom did something bad to hyesung, and its completely justified if hyesung doesn't wanna see her. However byul's is his own person he can make choices for himself, so yall dont have to say "Oh hyesung gonna be so sad, his son is meeting up with the evil woman who abandoned him." For hyesung she might be the most evil human being in existence but for byul she is just his grandma, the one who gave birth to his mother.
Im not saying she should be forgiven, but you shouldn't control about how another person should interact with another person just because you have a bad experience with them. And hyesung isn't even mad at his mother, hyesung just felt like he didn't need her, he didn't hate her he just felt like she is just a stranger now. If yall keep this up you just make yourselves sound like immature thirteen year olds.
