An interesting story about manipulation, mental health issues and abuse in many forms, whether it be domestic violence, bullying, intimidation, imitation or victimisation. If i was involved in even half of that i'd run a mile, let alone putting up with all of that at once. The ending at least for In-Ho was great as he finally got to follow his dream without the drama but still with a psycho sister who hadn't changed a bit, but Seol ended up in a mundane boring life (free of insane drama thankfully) but she deserved so much better such as with In-Ho who genuinely loved her and would have treated her properly. I gave this a 7, only because the acting was good and the talented piano playing was incredible and he's cute too. That ending though? Ugh.
