well, it's Kangwoo here and Sangwoo there
i hadn't started reading but killing stalking was the first thing i thought of when i read the plot. now i'm not sure if i wanna read this but what do you mean by slightly different?
first letter difference
I haven't really read this either. Just the plot summary as well and the name. In both, the uke are stalkers who stumble upon what they shouldn't and realise the seme's true colours. Hopefully it'll be well executed, even if it heavily relies on the killing Stalking for inspiration.
This seems like a slightly different version of Killing Stalking...
