You and Xingqiu have been friends since childhood, but there's one thing you never understood—Xingqiu's gender. Finally, after so long, you gained the courage to ask:

Xingqiu, are you ....male or female?

Xingqiu looks at you with a blank expression in the eyes and says:

We've been friends since childhood, and you don't know my gender? Do I really look like a female?
