Suddenly, after a few months, I realized I don't know what happend to ML's mother. I watched many episodes in korean, so maybe I didn't understand something. Can anyone tell me if she was murdered? Or is it mistery?
Edit: Sorry for possible spelling mistakes, I'm not a native speaker
The father said he truly loved his wife, but his wife loved only an illusion, and that made him dissapointed and it triggered his murderous acts, killing his wife first thing, so basically the father became a serial killer after then and found a young boy (Baek Heesung) to accompany him since his real son wasn't capable of hurting anything!
