TFW when ur so burnt out from an office job that you let a stalker be an invisible househusband/sexual outlet
surprised not a psych tag yet...tho other than the narrative? framing it as the coworker being the stalker (which might be 'outed' soon if he recognizes the handrwiting) i half expected it to possibly also be a one shot where he was so stressed he hallucinated it or it's some ghost/tulpa or so lol
