For this one-shot you and Mirio are already in a relationship.
I hope you enjoy. ^-^
I apologize if it ended weirdly.
" Mirio...Why?" You pouted , Feeling mirio press a kiss to your cheek. Mirio chuckled , Giving you a bright grin. " You deserve affection (Y/n). It's proven to make people happier."
" Is that a thing?"
" I...don't know , But...Kisses!" Mirio perked up , Placing multiple kisses to your cheek.
