It's implied that he actually knows, Yu-er just doesn't know that he knows.

Yes
If yu'er is the mute one, how on earth does he doesn't know that the ml knows that yu'er has a dick?? I don't understand
We virgin so can't answer that
I see... so he already know.. I want to see more happiness and cute stuff
Greattt!! Thanks (≧∀≦)
How can your gender not revealed when having sex like, isn't the feeling of an asshole and a pussy different?? Even if you turn of the light or hiding the dick, it still feel different right
