Even though he has a perfect boyfriend, he still wants to break up. Even though he is unsure about his decision, he still wants to break up. Even though he doesn't know why, he still wants to break up. That's him- Bang Yongguk. He wakes up this morning with his mind is zero, his body is stiffing and his soul like he lost it. Conclusion is his life is so miserable in the early morning.

Yongguk goes to their special place with his mind replaying all the good memories they had shared and it works when he thinks it again, should I or should I or not? His expression change when he got a phone call. A call that totally changes all of it. He feels stupid, he curses himself. What exactly the call is? Who calls him? Why he reacts like that? 

In the end, do they break up?
