I like the premise and the plot, but the direction of the female character is a bit frustrating to watch. She's an adult, she's a school teacher, and she's 18 years older when she reunites with her childhood ex, yet her behavior and reactions are worse than an adolescent. Just at epi 3 and I'm ready to throw in the towel without even caring about why they wrote the character to act this way. I love k rom com, but I shudder when one of the characters are written poorly... it makes it hard to "root" for them. She's a bit too ill-tempered and aggressively angry for me to hand her off to that fine Korean Ji Joon just yet. My rule is to give a drama 3 episodes to draw me in; but meh.
