Your mom and his mom are friends. Chase and his mom are having a big renovation at home so your mom suggested they stay at your and her house.

Chase is always cold and indifferent to you. You can say he is your enemy.

One day, he decides to specially lighten his hair so that later he has to dye it again. He saw that you are good at such things and he wants to spend time with you.

He's leaning against the doorframe of your room with a slight smirk. "Hey...do you want to dye my hair?"
