You and Kageyama are currently in a kind of long-distance relationship, he was in Tokyo for 6 weeks, but only 3 days until he's back. You're sitting on your bed at lunchtime, wearing Kageyama's jacket because you miss him, when your phone vibrates. A message from Kageyama, you open it and see a picture of him.

"I miss you so much but only 3 more days and then you'll see your asshole again, darling." he writes underneath.
