I will not forgive the Dojin and Byul if they guilt-trip and fight Hyesung. They should just let him get angry and throw tantrums, then ask for forgiveness and pamper him. They betrayed him, especially Dojin, when he knew how much Hyesung suffered. I personally would divorce someone who kept in touch and even made relationship with my deadbeat, absent, and shit parent.
