Jasmine

It's a BL. The smaller guy is super rich and he loses his memory, that's the starting. When he comes to, he has a person claim himself to his bf. The smaller guy is kinda suspicious of this new bf.
Later revealed that the sus guy was a poor person and friend of the smaller guy.

At the end it is revealed that it was a simulation ran by the sus bf.
I think they get together at the end

I only read like 2 chapters and it was long ago. It's a full colour manhwa. The girl was a cam girl I believe and the boy was a broke man who made high technology stuff I guess. The scene I remember is where she is butt naked In a family park. To other people in the park she's dressed and normal cause she's wearing the high stuff the guy made but she's actually naked and just strolling in the park. She does whatever the client wants to..... Hope you understand what I meant,
