Sang Doo! Let's Go to School

This outstanding drama follows desperate and devoted single father Cha Sang-doo (Rain) who becomes a gigolo to pay his daughter’s spiralling medical bills.  A chance encounter leads him to his first love, Eun Hwan (Gong Hyo-jin), and although ten years have passed and they were forced apart due to circumstances beyond their control, he still loves her dearly, but unfortunately there’s a catch – she’s engaged to someone else.
