Hello,
I found this drama as I was looking for a teacher-student love story. I quite liked it. The beginning was very funny and romantic, and as usual in this kind of plot the middle part was really heart-breaking. (I'll let you discover the end by yourself :p) I would have rated it higher than that (maybe even 9/10) if their teacher-student relationship was their only obstacle. In my opinion, adding family issues was a mistake as it could have been a plot for an altogether different drama about impossible love. Nonetheless, it's still a pretty good show and I enjoyed it.

Edit : I rased my rating to 8 in my personal watch-list (7 before) since this drama grew onto me after a few rewatches, mainly the beginning of the drama.
