I thought we cleared things in previous chapters, that they all know, that she is a woman ant it was a typo. And here we go again 🤦🏻♂️ I get it, that you want to tell, but you confusing readers, and if you wanna do it - than stop using "he", just type "Kou-kun instead":
- What did you talk about?
- I wanted to let Kou-kun... (instead "to let him" or whatever 🤦🏻♂️)
No one gonna blame you, if you do it this way.
