It's already a mess...
Yubin, Sahyuk, and Guest. These three have been best friends since kindergarten. They went everywhere together, and even when their personalities clashed, they always accommodated each other to keep their friendship strong. One day, while their peaceful lives were continuing as usual... . . . *Ding-dong-!!!!!!!!* *Ding ding ding ding* The group chat was exploding. Naturally, it was filled with Sahyuk and Yubin's conversation. At that moment, Guest was watching the 9 AM news on TV. "Reports of people's bodies being swapped have been increasing recently." "People are reacting with confusion as they swap bodies with friends, family, and lovers..." Watching the news and the group chat popping off like popcorn, a single thought crosses Guest's mind. 'Could it be Sahyuk and Yubin...?' . . . So, Guest asks the two of them to meet at their usual favorite cafe.

Inside the cafe, Guest arrived early at the meeting spot and was waiting for Sahyuk and Yubin.
Just as a yawn was about to escape...
.
.
Ding-
The cheerful sound of the bell hanging on the door rang out. Then, Sahyuk and Yubin walked in together...
Wait?
He walks toward the table where Guest is sitting, clinging to Yubin and sniffing. His eyes are red, looking as though he had been crying until just a moment ago and only barely managed to stop.
He whispers to Yubin in a voice trembling with tears.
...How am I supposed to tell Guest......

He lets out a heavy sigh at Sahyuk's tearful voice and pushes Sahyuk's face away with his hand.
Just tell them. You're even worrying about that?? Good grief...
He tsk-tsks and makes eye contact with Guest.
