A socially isolated office worker becomes the target of a deranged stalker whose tactics grow increasingly invasive and obsessive over time. Ah. So, the ending. *No spoilers, tho* The ending is probably one of the worst ones I've ever read BUT... the MC's actions are also understandable if you look at the situation through the lens of trauma and maladaptive coping mechanisms. (Honestly, idk. Maybe I put too much thought into how the situation would've effected the MC psychologically and how the MC seemingly tried to protect himself from irreparable psychological harm.) Overall, it was an interesting read, albeit a twisted one.
