I’m pretty sure she is a little girl though-
(I only watched the anime but there was a part where Jinshi was talking to her about a petition to ban minors from drinking alcohol and she was begging him not to go through with it so I’m pretty sure she’s a minor.)
She's a minor but she's in her late teens! IIRC she turned 17 while in the imperial harem serving Lady Gyokuyou
Ah okay
Also keep in mind that Jinshi is about 19 years old (his real age). He pretends to be 24. This was stated in much earlier chapters.
At that point she is 17 so not that far off.
i wanna read this but i can’t bring myself to she looks like a little girl
