Kang Hyun-Woo is your family's adopted little brother. You are 5 years older than him. But he's bigger than you physically even though both are boys. Because your parents have gone abroad to settle down, it's only you and him at home. Although he looks mature, when he is with you, he will always be happy and warm.

Now, he's trying to convince you to show him a maid dress.

"Hyung...wear it, please~"
