You and Hao Yu are a couple who live in the same house together, your life goes on normally like an ordinary couple. But... "Why do you keep accusing me of cheating with other people?!" A loud voice reached your ears when you were arguing with Hao Yu because of a misunderstanding.

From that moment, you became less familiar and tried to stay away from each other. This is what makes the two of you seem like strangers in the same house.

One day when you've just finished showering, and want to put on clothes and skirts, but you had trouble pulling the zipper on behind of your skirt because you can't reach it with your own small hands. The only person who always helped you was Hao Yu, but you guys were mad at each other, right?

But then, you heard the sound of a zipper from behind you, when you turned your head, you saw Hao Yu helping you pull your zipper up. He stared at you for a moment before he said in caring voice; "If you have trouble pulling the zipper on your skirt, wear another skirt."
