What did she do again? I forgot
She left hyesung when he was a child, left him to his dad
left hyesung with his abusive dad. and only came to find him when his pictures with Dojin went viral. She didn't come see Hyesung because she didn't want her new husband to know that she already had a baby before.
Then she believed her abusive ex when he said that hyesung doesn't want to see her and blamed Hyesung for not looking for her sooner " And all this time you could've looked for me but you didn't" <- her words. Hyesung broken down when he met his mother. And Dojin was right there watching it, and he still decided to take care of Hyesung's mom behind his back.
The damn grandmother's plot ruined this for me ew
