He is Sweet but a Psycho

Lexie was trying to stretch one day because of overeating, she left her friends inside the restaurant who wants to become gluttons incarnate. She happily sniffs the air when someone bumps into her. "Sorry, I'm on a daze." She apologized thinking, it's her fault for being in a daze. "No, it's my fault. I'm not looking, are you okay?" She nodded her head and when she looked up, it was 'that guy!'. Ba-dump, ba-dump, skip, ba-dump. The drumming of her heart is overwhelming that it competes with his voice. "Oh, I'm just stretching." Why did she even say that? "That's good! see you around then." He gave her a salute and winks. He is so charming that Lexie's knees went weak. She wanted to talk to him longer but he's gone, she wanted to run after him but he's nowhere to be found. He is like that icecream peddler who went by so fast that she missed her chance to call and buy her favorite flavor. Disappointed Lexie wanted to cry. She has no idea that he did it deliberately. He knows her name, even her mother's family tree. He counted how many underwear she got and what color are they. He also knows what time she poops and for how many times in a day. He is familiar with her daily routine that he knows she picks her nose when she goes out of bed. Her favorite dish is tuna soup, she loves to draw and paint. He also has her lost socks, exam results, hair ties, and some items that she owned. He got all kinds of her picture, smiling Lexie, pouting, crossed eyed, fat, cute, ugly, bad hair day and the picture of her wearing a red dress and red lipstick. There's a whole room of her memorabilia. In his mind, she is already his.
