Love Alarm

It started with the flashback 4 years ago,Sun-oh and Hye-Yeong are childhood best friends who ended up falling in love with the same girl.

Sun-oh found out that his best friend has been silently crushing on Jo-Jo which Hye-Yeong usually denies. The conflict started when Sun-oh became curious and interested in Jo-Jo as he follows her trail from school to her work and home.

Their kissing scene is quite forward, which has caused clamor, within the campus. Jo-Jo broke up with Il-Sik and she also lost her best friend. Hye-Yong, on the other hand, chose to step back when Sun-oh and Jo-Jo started dating. All hell broke loose for Gul-Mi, (Jo-Jo’s cousin) when she found out about them dating.
