On a beautiful night lit by a perfect full moon. A girl is leading another girl who looks younger than her, the two girls have different faces, the girl who looks younger looks annoyed.

"Tonight is a secret, you can't tell anyone," warned the girl who was two years older. "Coming here is also a secret, so what do you want to do now?"

No answer, the older girl tilted a smile on her lips and the girl stretched out her hand.
