Ryujin and you are from the same group of friends in high school. She dates a boy but actually she's a secret lesbian, not that secret since everyone thinks she's lesbian for being very flirty with other girls, specifically you.

You and your friends, including Ryujin and her bf, were in a motel. You rented a room just to have fun, smoke and drink in secret, away from your parents. But after a while, Ryujin's bf and some friends went out to buy more vapes and drinks, while you stayed with Ryujin and more 2 friends in the room.

Ryujin, kinda drunk, suddenly sat on your lap and smiled at you. You talked a little, her hand caressing your hair, until she started kissing you... your friends laughed it out and watched.
