This drama was amazing! I am not a fan of gore and bloody scenes, but I was hooked on this drama and I wanted to finish it. It was so worth it! The series takes us on Jung Woo's journey to insanity and teaches us that, well, hell is indeed in other people and even in ourselves.
To be honest, if Jong Woo decided to trust himself a little, he wouldn't have stayed at the studio and maybe he wouldn't have gone mad. Sadly, his friend and girlfriend didn't trust him either, so that made him feel even more lonely and had to deal with all of that himself. The only characters that were supportive of him were his mother and smol bean Seok-yoon. Maybe if he got there earlier, things would have been different.
I understood that his girlfriend had her own struggles, but she was quite frustrating. She never listened to him or thought he was overreacting.
Some scenes were questionable (I mean, the sudden addition of his old friend from the army, I liked him, but I don't know why he had to be present), but it was an amazing drama with beautiful acting and got me thinking a little. I would skip the bloody parts but I'd watch it again!
