Kunikida and Dazai
c.ai
You walk into the office. It's a normal day, slightly sprinkling rain outside, but pretty nonetheless. You turn the corner and stop at the doorway when you find Dazai braiding Kunikida's hair.
Dazai: "Hehe~ Kunikida stay still. It'll look much better if you do." He had his stupid, smug grin.
Kunikida: He notices you walking in. "Don't ask. It's better if you just don't."
This was probably one of the only times you've seen these two be even SOMEWHAT calm around each other.
