Their first time is def unconsensual and kinda an unfortunate situation for both parties as ML doesn't actually really remember their first time because he went into pheromone shock meaning he looses consciousness and doesn't have control of his body (still didn't need to be written the way that it was as it's throws the flow of the novel off and I feel it's not consistent with other times ML goes into pheromone shock around MC). Other than that scene though, ML never does anything against MC's will. It's truely a beautiful and cute novel of healing and both individual and relationship growth and it's a short read that I would recommend to everyone. So, don't worry, ML is very green forest within the novel.
It was non-con in the novel, heavily dub-con at best.
MC had to practically force himself to agree this is the only way to calm him down and was very clearly not in love with ML at that point (in heavy denial at best which still doesn't equal consent). He was against sex, and he only agreed to suck him off because he hoped that's all it took to calm him down.
Almost the whole scene consisted of him thinking about how bad it feels and how much it hurts and wants it to be over. It doesn't matter why it happened. The dumb af pheromone shock idea was just an excuse for the author to write a rape scene, that's nothing new.
I'm not putting the whole chapter but here some lines to show you that mc wanted it:
Initially, Heeseong welcomed more, accepting Yoon Chi-young’s kisses WILLINGLY . His mind muddled, he even licked Yoon Chi-young’s member offered to his lips like ice cream.
With each touch of Yoon Chi-young’s, Heeseong WANTED to feel that tingling sensation even more
Even the pain felt like pleasure. Saliva dripped from the corner of his mouth, mixed with groaning moans. It seemed not Yoon Chi-young, but he himself was the beast. His white tail rapidly tapped Yoon Chi-young’s lower abdomen, REVEALING the AFFECTION he tried to hide.
Yet, amidst it all, he WISHED Yoon Chi-young would keep thrusting hard
for the knotting part:
Overwhelmed by the intense pleasure, Heeseong started to sob softly.
Heeseong clawed sharply at Yoon Chi-young’s chest, the PLEASURE seemingly endless within him.
“Do you like it that much?”
Breathing thinly, Heeseong nodded unknowingly. HIS first EXPERIENCE WITH SEX AND KNOTTING WASN'T BAD ; it felt addictive. Heeseong reciprocated the affection, leaving small bite marks on Yoon Chi-young’s shoulders and willingly presenting himself for more by draping his upper body over the be
Looks like they changed the sex scene A LOT from the novel which I'm immensely grateful for.
In the novel it's basically just rape from start to end after yapping about trust and shit. I was hoping they'd change it but didn't think they'd actually do it.
