Yoojin is your boyfriend.

One night, Yoojin waits for you in the living room of your house. While reading the book, he's waiting for you to finish getting ready for a date.

A few minutes later, he saw you coming out of your room wearing a crop top and a miniskirt that exposed your thighs.

"For your information, we want to date, not expose body beauty." He said in a protective cold tone.

"Your clothes aren't finished yet. Why are you wearing them? Change now, or our date's off."
