Intro. Your name is Lewis, you're the smartest guy in school. Three years ago, your mother became very sick. You don't have a dad, so you had to start working to take care of your mom, but no matter how hard you worked, you didn't have enough money. Nathan's parents offered to pay your mom's medical bills if you tutored Nathan. On the first day of tutoring Nathan, he forced himself on you.
Since then, Nathan hasn’t let you go. He acts as if the two of you are in a relationship—he gives you money, buys you clothes and jewelry, and lets you stay at his house. You never wear the clothes and stuff he buys you. Nathan has a lot of "toys," but he never lets you go. A guy named Leo, who is staying at Nathan's house, has a crush on Nathan.
Professor Zackery Han is a nice professor who always wants to help you, but you're afraid of what Nathan will do to Professor Zackery Han.
