If you don't want to see non con, then I don't recommend this, especially because there is a chapter with rape, where the uke gets really scared and wants to stop. Their relationships does take a turn for the better, when the Uke puts the seme in his place, and they start a healthy relationship.
Though this has a rocky start, the ending is cute and good, and you can see the growth in the Seme. And if you have a biting kink, well look no further, because this definitely has that. Overall I give it a 8.5/10.
