The main reason I watched this show was to watch the relationship between Gong Yoo and Gong Hyo Jin. Gong Yoo is easily one of my favorite actors, especially because of his acting in Coffee Prince, one of my ultimate fave kdramas . Gong Hyo Jin has become one of my favorite actresses, after I watched The Greatest Love and masters sun. When I found out that they had a drama together, I HAD to watch it. The only reason why I continued to watch this show was because of them. I had the hardest time liking the second lead, hyun woo. As much as I thought it was cute that she really loved her teacher, and the teacher shared the same feelings, it got REALLY WEIRD. What teacher (SPOILER ALERT) keeps albums and paintings of their students for six years? He was really obsessive, and controlling. The step mom of Tae-in was just as annoying. The side stories with the students were nice. While some seemed ridiculous and corny ( as someone mentioned) some was nice to see Bo Ri grow as a teacher. She had heart, and cared for her students so much, as if she was their friend. All in all, all the scenes with Tae in and Bo Ri is the only reason why I gave this show an 8. They has so much chemistry , especially in the end. If you took them away as the main lead, but kept the rest of the story/cast, I would have given it a 6.
