In order to be able to fulfill his contract with YG, TOP has to leave the love of his life, Byul.

In a fun twist of events, 5 years later Byul gets a job at YG as a assistant. She assumed TOP had completely forgotten about her and wouldn't remember her if he saw her again.

Althought reality is never as easy as we hope it to be and things turn for a worst when Byul starts feeling emotions for the shy but charming Taeyang, emotions she only thought she could feel for TOP.
