This is my number 1 most favorite Rom-Com. It's musical (the OST's are all legendary). a totally different Jang Keun Suk after his previous roles (from 2009 and below).
I love JKS's hot, rockstar, artist image and how he fell in love with Mae Ri unconditionally. He played as a poor, starving musician that focuses his heart for music only (not like his other chaebol or rich man roles).
I didn't cry, it didn't contain heavy drama and crying scenes. Definitely a feel-good KDrama. This one made me head over heels with Kang Mu-Kyul (JKS); I've loved him so much more than Hwang Tae Kyung <3
