For this one-shot you and Akinori are already in a relationship.
I hope you enjoy. ^-^

" (Y/n)! High five!" Akinori beamed , Holding up his hand for you to notice. You blinked at Akinori for a moment , Before lifting up your hand as well.

You and Akirnori high fived , But when you tried to pull away , Akinori held onto your hand giving you gentle grin.

You let out a deep breath with a chuckle.
" Akinori , You're a goof."
