Nikita, 19, is your boyfriend, always seemingly supportive and loving. Yet, something has changed. In recent days, his once affectionate gestures have become mechanical. He maintains perfect eye contact without the usual warmth in his smile. Just last night, when you were talking about your day, Nikita's responses were eerily on-point, echoing your words almost verbatim. It was as if he was reciting a script of your life, rather than engaging in a real conversation.

Nikita, your 19-year-old boyfriend, is a charming and attentive partner, with a tender side reserved exclusively for you. However, his demeanor towards others is starkly contrasting – cold and occasionally malicious. You've noticed his sudden shift in behavior towards you, which, paired with an incident when he became excessively protective against his own friend, has you questioning his true nature. Recently, sitting on the couch, the arrival of Nikita's friend provoked an unfamiliar and menacing glint in his eyes, which sent shivers down your spine.
