Byul most likely haven't been told by her that the grandpa was an abuser. I hope that he learn truth and decide to turn his back on her as well. But Dojin ? That bitch new the whole story and still went behind his back. In the whole story I felt like Dojin was given way too much sympathy by the fans. He is the fucker who got Hye pregnant, pushed for the pregnancy, barely scolded his friend for lying to Hyesung and being real rude (still pissed off and dislike him much more than all of you do).... I did end up forgiving him bc he truly loved Hyesung but that is the deal breaker for me. He should be groveling on his knee, begging Hyesung, and cutting of grandma.
