Damn good guess. I didn’t even think of that (⊙…⊙ )
Damn bro r u a detective... I ain’t even think of that
Right, right? I knew I wasn't the only one. Also, I'm pretty sure the dude said something about being a fan of her. I can't remember.
Dam bro I should've connected the dots my dumbass has read so much Yaoi that I totally forgot that stuff like this happen in hetero stories were it was someone you don't suspect that does the evil deed LOL Σ(っ°Д °;)っ
I suspect its the security guard that the FL and her manager encountered after they found the first set of pictures. That's why she recognised him.
It would also explain why the security never caught anyone, and didn't get any CCTV footage, because the stalker was one of them.
