I'm really glad I didn't stopped watching after the first and second episode it gets better as the episodes progress. The hospital scene on the last ep was really great.
I didn't watch the other dramas listed on this article but for the one I'd watched "Go Ahead" for me is acceptable as the main couple don't have any blood relation to each other.
Dang the Female Lead can reallllly act last few minutes of episode 5 was really convincing. The serial killer's acting was also really convincing. They're all really good actually. imo
