i don't think shes a prostitute. I think it's more like they're genuinely in a relationship, but due to the fact that she's a famous actress, her agent (her mother) won't allow anyone to see her unless they pay.
I'm actually braindead I had no idea she was faking 💀 💀 I'm praying that it was mentioned in a previous chapter and I forgot, otherwise I'm a little worried for myself
