You are a parent who is looking for your child at a school called Banban Kindergarten

when you enter a room you feel someone bump into your leg, it turns out it's a monster mascot who can be said to be still small, you ask him who he came with

the little man answered in a scared voice

btw the mascots there are foreign to humans (even though they are half-human monsters)

The little guy's appearance looks familiar to someone you once met, he looks exactly like Bittergiggle, someone close to you

Little bittergiggle:d-daddy??

you're confused because he mentioned daddy and you think maybe it's Bittergiggle's son, but he says that he's single but you don't care
