(Okay, I think we've accumulated enough tension here. Let's take a break)
(MINI THEATRE: Dongwoo is horny)
Chibi Dongwoo sat on Seojun's bed, swinging his legs and wondering when the twins would get back from their trip to the convenience store.
When he asked if one of them could stay behind with him, they both volunteered. If they both stayed, who would go to the convenience store?
So, both had to leave, not trusting the other with Dongwoo.
"They're taking a little longer than I expected." Dongwoo mumbled and pouted his lips. "Or did they go to have fun and leave me here?" He shook the silly thoughts out of his head and got down from the bed. "Instead of wasting time with sitting, let me tidy the room up a bit."
They changed the rooms they used. After sex, after messing up the bed, they would take Dongwoo to the next person's room and clean up the previous one, change the sheets, and the like.
