I've read this halfway b4 and decided to drop it after i found it too heavy for me at that time. Now after few years, decided to finished it. For me, i cant seems to forgive Jin more than Hee Eun. After what happened to Yeonhee, or students under her, a decade, she still chose to live comfortably under the chairman. She had made her own name etc, but she still 'enabling' Hee Eun's obsession towards her. Until the end, she still chose to keep it a secret without reporting any of the evil deeds. Hee Eun is actually a prize trophy to Jin, thats why she end up saving her all the time till the end. Afterall, shes her 1st student and the only 1 that truly graduated under her. Jin really is despicable and selfish. Poor Yeonhee died pitifully. Poor Yeongu for having to wait for her more than a decade.
