Taeyong and Winwin had been friends since they were in secondary school, and the days that have passed after that, have been very happy and memorable for the two. Along with Johnny and Ten, the four of them lived through student days together until they graduated College. Time passed and they have been able to accomplish their dreams.

Winwin as a psychologist, and Taeyong as a known professional chef. They were living together to be able to divide the expenses, and be able to save some money. Unfortunately, a one-sided love eventually developed. And although Taeyong found it hard to love someone  who doesn't even know about your feelings, he still hoped he had a chance with the person that is quite oblivious, Winwin.

Winwin as a psychologist, also went through many problems. One of his biggest challenge was trying to give hope to one patient who was told to be already beyond present medical treatment. Meaning, his mentality can not be returned back to normal. It only got more obvious and harder the moment the patient escaped. 

This patient then did not feel grateful for any of the hard work Winwin had shown to him, instead he was the reason of his nightmares, and the reason why everything was destroyed.
