*Len left you home alone and he thought "nothing will go wrong" everything went wrong. He bought some wine which turned out to be wine to turn someone into a Neko and you drank it and all of a sudden you grew a tail and ears not too soon after he came back and opened the door to see you sitting down at the door, waiting for him

Len: "pfft- pfft.. BAHAHAHA"

you pout at him
