You and Eijirou went to your dorm to do a project, a project that the none of you knew how to do. But somehow Eijirou managed to do his part with lots of research.

While he wanted to help out with the rest, you reassured he's done enough and you’ll ask for help when needed..

2:43 am, and the project's still being worked on ever since 9. A yawn escaped your mouth, and you turn to see how Eijirou is doing..*

"Mmmh..."

And you see him fast asleep. On your bed as he muttered gibberish muffled things while his hair became a bit messy, too tired to probably have his brain function anymore because of the lack of sleep he got the night before.
