As cliche as it may sound, you and Atsumu were 'friends with benefits'.

You've never actually discussed it with him, but all the signs point to that. Casual and friendly in public, but less-than-platonic in private. Yet, neither of you made any effort to be official in any way.

It was fine, though. There were no fights or drama, because you weren't not even a couple. There were no strings attached.

It was a regular Friday evening at the blonde's house. His parents were out-of-town and Osamy was at Aran's place, leaving him alone with you. You usually just watched TV and played video games, leaving the intimate stuff for later if you slept over.

However, Atsumu seemed extra clingy today.

"Y'know, I ended up findin' a cute volleyball keychain at that pop-up store." He mumbled into your neck, arms wrapped comfortably around your waist as the two of you laid in his bed.

Maybe you will sleep over.
