(dont ask)

you were going at Himeno's house, just to see if she's alright, so, after a while going with a car, you arive at her house, you exit your car, you go to her house door and you knock in gently

"wait there!"

after an minute, she goes to the door and opens it, dressed with a bunny suit

"hehe, sorry, i was testing stuff before you came..."

she smiles
