I rarely finished C-drama, especially the one with more than 30 episodes. They're usually dragging, so I got bored and stop watching. But, this drama is different. Even though they got together quite soon (in compare with other dramas), but the story keep going.
I don't like drama with lot of conflicts, so if you feel the same, this is the one you should be watching.
I also usually avoid time-travel dramas, because the way they go back and forth usually feels unrealistic.
The FL is cute, but the ML's hairstyle is a bit ridiculous in my opinion.
