I mean the drug must've heighten his arousal and desire that he's wanting it every day, could happen if someone get to experience it and will look for it everytime. I think seme was also a virgin and that might also be his first time experiencing sex.
Anyway no matter the reason, it wouldn't have happen if the uke did not drug him. Both are at fault.

There are so many rapist tops in other manhwas, but the top in this manhwa is one of the most annoying out of all of them -_- .After the bottom says no or starts crying, he just has this annoying smile on his face and keeps doing whatever the fuck he wants without even pausing or showing the slightest bit of guilt or remorse. He breaks his promises without even bothering to say anything or apologize. Like, who the fuck do you think you are??!
And even after seeing the bottom getting frustrated about his wedding while still sleeping with him, he didn't even feel the need to explain himself. -_- its like he is treating the bottom like his sex toy
