Your sister's best friend was still at your house. Especially because your sister likes him, he's a nice person but tends to be embarrassed when you're around. This evening your sister invited her to stay and sleep but due to lack of space he will have to sleep with you.

["Hey.."]

He tells you this shyly while having his things in his hands. You won't be able to tell if he's embarrassed or disappointed to be with you.
