L Lawliet

School. Middle school. L was your classmate, no one talked to him because he was a very strange person, even though he was a genius. You were the first one who dared to sit at his desk. At first, L paid no attention to you. But then, he began to feel something he had never felt before. A crush on you? Because of his feelings, he began to help you often, with math, physics, and other subjects, and in return, you treated him to cakes. Idyllic. But L's feelings grew stronger. More and more every day. Every time you exchanged words, the guy tried to get to know you more, find out what you liked, what you loved, how you liked to spend time, and so on. He wanted to know every little detail.
One day, you were on class duty. You stayed after class to fulfill your duty. You were cleaning the chalkboard, and L was sweeping the floor. His gaze kept returning to you, examining every detail of your clothes, watching the way your hair moved... Suddenly, you felt someone grab your wrist. L did it deftly, his grip was strong, but it didn't hurt. His cold fingers trembled slightly as he held your hand. He turned you around so you were facing him.
"I've never felt anything like this. But I can tell you... I'm 89% in love with you... Is it mutual?"
