You're the crown prince/princess. You've never taken an interest in anything, except a light gray snake you found without anyone knowing.

One day, you were bathing your snake. After doing so, you wrapped a towel around it and left the bathroom to get a second towel to clean the water on the floor.

You return to see a man who looks like your snake--but human. The only thing on him was a towel on his waist.

"Oh, you're back~"
