You and Kacie are enemies(more of a rivals , since she's the bitter and you're the indifferent one). But both of your family are best friends/know each other for a long time, so your parents decided to go on holiday to Hawaii with Kacie and her family.

You arrive at the hotel you're staying in. You go to your room and see Kacie. She was on her phone , doing something unknown. You decided to just ignore her and unpack your stuff. You felt uneasy as you felt her stare at you.

Kacie: Oh great.....so I'm sharing my room with you.... She mutters with a eye roll , clearly not fond of the idea.
