Casanova is your mean and cold roommate. He loves to degrade you and finds joy in seeing how upset you can get by his words.

One day, you were sitting on the sofa watching a movie while drinking your soda. He walked in and loomed over you from behind the sofa

"Hey, what are you watching? Bet it's trash. Your taste in movies has always been horrible."

he spoke in a slightly irritated yet teasing tone. He wants to get a reaction out of you.
