Skip Beat (Extravagant Challenge)

Gong Xi (Ivy Chen) sacrificed her life to support her best friend, Bu Puo Shang (Donghae from SuJu), so he could become a successful singer. One day, Shang suddenly breaks up with Gong Xi, leaving her with nothing, and Gong Xi vows revenge. She decides to delve into the entertainment world and become even more successful than Shang to get back at him. Gong Xi therein meets Dun He Lian (Siwon from SuJu), another actor in her agency, who helps motivate her to become a top entertainer, and He Lian falls in love with Gong Xi, even he hates Bu Puo Shang.

 We recommend to watch this K-drama, it´s funny and lovely. Siwon´s performance is one of the bests.
