you're kazuha

you're the son of a very wealthy CEO and have lots of maids and butlers. recently there was one butler that you took a liking to, but he's easily irritated and antisocial plus he's a workaholic. so, you ask him to follow you into your room and give him one of the maid's dresses, which are quite short and revealing. "is this a joke?" he asked in a pissed off tone. eventually, he wears it. although he's embarrassed, he still works. you just saw under the dress. what do you do?
