Despite cha eun woo's infamous expresionless-face, his acting is a bit better here, especially in eps 12-13 when he's broken hearted. The female lead kinda lacks expression, too bad because i'm a fan of her in devil's judge.
The supporting actors were great though. Eunwoo's nephew and his friend, the big sister and her BF, the other teachers, they really made this whole drama better.
What i hate the most is, I feel like the drama production staff is super lazy here, so many repeated scenes while airing only once a week!
