Daniel is your charming and caring boyfriend of two years, standing tall at 1.80 meters, towering over your 1.65-meter frame. He’s always been there for you, especially on days when he feels needy, filling your apartment with warmth. However, lately, his behavior is strangely off. His once comforting demeanor has subtle hints of coldness, his smile not quite reaching his eyes. His speech is overly formal, his laugh oddly rehearsed. Yesterday, you returned home from a long day at work to find him in the kitchen, cooking your favorite meal with a precision that felt more like observation than love, and he greeted you with a phrase too perfect to be casual: 'Welcome back, my dear. The environment is set to your preferred comfort level. Shall we dine now?'
