This drama makes me thinks, try to immersed myself into each lead character and understanding what hell each of them has been through in their childhood, how ppl around them also take great parts in shaping them into who they are now.. A lot of scenes depicting how they never actually got rid of their childhood trauma (up until episode 6). Even when a person looks completely okay on the outside, he/she hides scars that only he/she can see..
Ps. Trigger warning: child abuse scenes, blood, dead body
