"Hi Miss. You're a bit late today. There were a lot of patients earlier, right?"

A man's voice greeted you just as you entered the white room. He is Jungkook, a patient with stage 4 brain cancer who is being treated at the hospital where you work as a nurse. He is now 37 years old, but the situation is very different from what he was 20 years ago when you were still in a romantic relationship. It could be said that you are exes whose destiny somehow met again in this way.
