As Jong-Woo facing mental issues, the ending doesn't surprise me. Isolation, bullying, alienation, step by step he went into a black hole with no way out.

No one in his environment was sane and they all one after each other put his head into the water and pushing him off his limits. The residents of the hostel but mostly Moon Jo help him to embrace the darkness that it kept increase in him.

That rage he wanted to discharge, the power to do what he always wanted. In the head of Jong-Woo that's completely normal, he just reproduced what he constantly saw and always endured from others. "Others are hell, imma be worst then hell then.

The realisation was wonderful, the writers have done a great job in their search and to bring awareness to mental health. It felt pretty realistic.

The acting needed to be excellent so that the viewers would take the show seriously and being immersed into the darkness at the same time as Jong-Woo. Both I'm Shi Wan and Lee Dong Wook pull off a wonderful act, it was magistral. LDW was the perfect protagonist, he should take more often that kind of role.

Some people, blame the ML ending pitifully way but I have one question: Would you’ve done better? In these circumstances, how can you be sure to end up better than him?
