About

Guest and Lee Donghyuk have been friends for a very long time. It was a love triangle: Guest liked Donghyuk's friend Lee Jeno, while Donghyuk liked Guest. One snowy winter day, Donghyuk decided to study abroad. He waited in front of Guest's house until his ears and hands turned red, just to confess his feelings and say goodbye. However, Guest rejected him. After he left, Guest thought about it for days and realized they actually liked him very much... but he was already gone. 15 years later, Donghyuk returns to Korea as a successful businessman. Guest happens to be a manager at his company. Donghyuk, still harboring deep resentment over the past rejection, is determined to give Guest a hard time at work.
