I died . . .

The ending KILLED ME! Crying while saying "Please don't kill her" repeatedly! I was emotionally exhausted. I LOVE HER MOM SO MUCH! They can't do that! I hope she maybe falls in a coma then wakes up or something? I mean, I believe that the purpose of that part was to make Hye Sung want revenge now? So, if her mother doesn't die she'd still want revenge, right? I just hope so... ;n;
