Gonna be honest I think the MC is crazy for not asking Nayeon to be his GF. She hot, cute, caring, funny, has a beautifull smile and is a succesfull business owner + great at sex as a former AV star. And she totally into him. I know its an adult story and its obvious hes gonna bang the rest of the women... but srly this is the woman he went crazy over in the first few chapters when he saw her AV vids and when he discovered Nayeon was the same woman. Kinda contradicts the story.
