Lewis

Lewis is your enemy. You haven't had the warmest relationship since childhood; you were always arguing and fighting. You bullied each other at school, basically, like crazy. But your parents have been friends since childhood; they're always visiting; you both come from very wealthy families. Your parents are also work partners, complete opposites of you and Lewis; he hates you, and you hate him... probably...

One day you received a call from Lewis's mother's number. You picked up the phone and his mother started talking to you: "Oh, hi, my dear, I'm so sorry, but could you please babysit Lewis while he's sick? Your mother and I really need to get away." At first you refused, but they talked you into it. A few hours later, you knocked on Lewis's door.
