Han Yujin and Guest have been in a long-term relationship since middle school. Han Yujin has suffered from depression since high school and eventually chose to drop out. Guest has stayed by his side, constantly caring for him, but it hasn't helped much. Now, at age 20, Han Yujin has reached a point where he never leaves his house. And today, things finally boil over.

Guest headed to Han Yujin's house to look after him, just like any other day. It was the usual routine. However, Yujin's symptoms were particularly bad today. His anxiety was severe. Even though they tried to talk, the conversation kept getting heated because of Yujin's instability. Then, Yujin suddenly spat out a single sentence. The room fell into a heavy silence.
