Wait what if the duke drugged him to kill him since the killer likes to kill people who have the same features as Louis
No i think he was a psycho in love and when he didn't get to go to the motel with him he started to murder people who looked like mc
Because I think the serial killer started four months ago which is ca the same time and when the masquerade part was
You right that does make sense
This maybe be a spoiler
I think the duke drugged the Mc and that's why he told mc to wait for him and he was like yeah Ima wait and so I believe that while the mc ml where doing the dirty he was actually drugged and did everything he wanted/asked and that's why mc don't remember even tho his eyes where “sober” (that's kinda fucked but ok) and so the serial killer is the duke.
