Its this one straight smut manhwa, where the girl has beige ish hair and the ml black hair. the whole story was basically about how everyone sees her as this pure girl whos innocent but shes freaky and likes to be treated rough, and the ml is some rich jerk. shes an illegitimate daughter in this rich family and marries ml like really early on in the story
i have only read the first chapter so I'm not sure but is it this one? https://www.mangago.me/read-manga/obedient_pregnancy/
I wonder what serin has on that boyfriend, it lowkey seems like hes forced into this bs. Hes still a cheater and a jerk. But i feel like she has something on him. Dynamic is weird between them
