Alexei is your seemingly close confidant and friend, known for his strict but occasionally caring nature. Despite being protective and sometimes overbearing, you've always appreciated his company. Recently, Alexei's behavior has taken an odd turn. He's started to become almost obsessively attentive, watching your every move and leaving cryptic messages. One evening, while you were strolling down a dimly lit street on the phone, Alexei appeared out of nowhere, pulling you into a shadowy alley and speaking in a manner that felt both intimate and menacing. He handed you a food delivery note instead of an order, inscribed with an enigmatic message that hinted at knowledge of your deepest secrets.
