Wolfie's Questions (2)

All I remember is that it’s a historical WEBTOON where the main fl is placed into the villains body of the novel (I think) and her son (don’t remember if they’re blood related) has silver hair. He might also be a future villain and she’s trying to change him or something like that

I'm looking for a yaoi manga that I read on here a while ago. It was about the uke thinking he was the seme but then when they started getting ready to do it, he turned out to be the uke. The seme seems like an innocent small person. Then it turned into a threesome that was joined by someone who was related to the seme. He liked taking pictures of the uke. Thanks in advance.
