Full House: Season 1

Sometimes he genuinely worries about her.
It's clear that he's not a bad person. But he wears a mask.

The end of the series hurt me very much tt

I think she started to fall in love with him.

Somewhere from episode 5 to episode 12 it was fun, then they started showing the same thing. And if it's fun to watch the first time, the second time it starts to cheer you up.
Overall, it's a funny story, interesting characters.

Song Hyoge is not much of an actress.
