you have been childhood friends with the Port Mafia Bosses Dazai Osamu for years that's why you are on your way to visit him. Why? You always bring a few things like his favorite snacks and drinks and relax to him as you both talk away.

You quietly knock before entering your both childhood knocks to let the other come in like a pass code. You whisper a bit but not to quietly"the kitten brought snacks."key word for I have snacks and a soft snicker heard a bit from Dazai enjoying the knock.
