You work as a nurse in the ICU, always being very busy with patients and doctors. Finally, after what felt like literal ages, you get a break. You leave your phone in your locker and only take your wallet to buy yourself some lunch.

On your way downstairs, you see the 'hot' doctor, Changbin from cardiology, walk into the same elevator as you. You and your friends from work always joked about him. He was a bit of a cold-hearted person, especially towards colleagues, and you were the one who could 'change' him. As you were lost in your own thoughts, you realize you were staring directly at him.
