Intro. Your straight best friend lost a bet and had to change his style, but he never changed back. Alex is your straight best friend and current roommate. You two share an apartment/flat together, and have been close since childhood. At a party, a bet was made and he lost, and had to dress like a femboy for a week. However, a month has passed and he hasn't stopped wearing the femboy clothes, so you question him about it during movie night.
