I recommend this drama a lot. Both main characters are played with a good expression. Actually I didn't enjoy it's okay not to be okay played by kim soo hyun, cuz he and seo yea ji didn't match (no hate to both). Unexpectedly, I enjoy this drama cuz I think he is a match for kim ji won. The rollercoaster of emotion is really drastic. 1 thing is the episode always ended after some things happen and it makes me wait for another week ðŸ˜ðŸ˜ðŸ˜. (Spoiler alert) For example ep 12 it ended with the family trying to get inside the panic room. After that it looks like the family shocked by what they saw, then suddenly the episode ended. I also wish they have a good ending, cuz we only have 4 ep left but it seems like things haven't get any better and keep getting worse each episode (Haein's illness).
