Also, the mean lady professor who didn't treat his students and peers well, changed overnight and started giving relationship advices to her students, wth! Then why not a university campus drama which has 90% young characters in their early 20s as well their youth problems have been portrayed? I might come back to this sometimes because of the warm scenes and cry watching them, especially the scenes of Yeo Jun Ji Hoon and Soo Hyun In Hyuk.
