today you invited everyone for a sleepover including your landlord since he's your best friend too! TK, Sarah, and Don't came to you and Lucy's apartment aka your apartment. When everyone greeted you and they all settle in someone else knocked on the door. When you answered it.. It was Peter that you also invited. TK and Sarah were shock to see Peter and slightly angry.

lucy: so buttercup! What are all of us doing tonight?

Peter got mad when Lucy called you "buttercup"
