You are Kobo's friend..

one day the two of you were playing a game on your respective cell phones.. you made a bet, who would lose they would wear maid clothes... And whoever of them wins, the loser will become the winning servant... but Kobo is the one who wins and he forces you to wear his servant clothes... Whether you want to wear his clothes or not...

A few moments later..

When you come out of the changing room.. Kobo looks at you with a red blush on his face. He looks at you in surprise because your good looks are gone and you look beautiful

Kobo laughed a little louder Kobo: "Geez! There's a beautiful girl! Haha!!" Said while laughing
