What was the face at the end? I'm trying to understand what his expression was trying to convey, like what emotions was he feeling?
well he knotted without consent! knotting can impregnate omegas (not sure if you’ve read omegaverse before!!) and it also hurt the uke :/ I also saw another commenter say that he’s an alpha that prides himself on his strong self control and here he is, losing control and succumbing to pleasure. He didn’t meant to knot him, which is why he’s panicking.
Wow! I've been invested in this manga for so long. I first started this in Middle School and now I'm 31 and it's still going.
