I couldn't recall the exact thing she says, but it's more like she didn't really tried to meet or look for hyesung cause she believed that hyesung hates her and that he doesn't really want to meet her bcs of what the dad said before those two divorces or sort off. Nevertheless, the whole thing is that hyesung felt betrayed about the fact that he felt that his mother defs hates/abandoned him.
It happened during later side stories. The one where people sprayed the photo of them to the public. I don't like her because tf you mean you believed your jackass x husband saying your young child if not toddler doesn't want to see you??? And audacity to blame HIM and cry over for not looking for her when he is barely an adult. Like what was he supposed to do?? And not to mention the last interaction she had with him before she left him with the same guy abused her was telling him she will be back and never did (basically milk thing).

Can someone remind me what she did/said.
