This light romantic comedy was entertaining and short (16 episodes only).

Story 8.5
The love story between  a rich egocentric charming heir of a conglomerate and apoor but kind-hearted school-teacher. Jae In's grandfather acted as matchmaker/fairy godfather, to bring the two seemly mismatched characters together.

Acting/Cast 8.5
Ha Suk Jin and Jeon So Min were perfectly cast as the lead characters.

Music 8.0
Music moved the drama  toward the conclusion.

Rewatch value 9
I watched this drama twice.  

Overall 8.5
The weekly scripts and the leading actors' performances kept my attention, as the romance continued on the incline.  I cringed at Jae In's fashion choices 90% of the time.  Ha Suk Jin/Jae In looked perfect, otherwise.
