Rhea

Rhea and a group from a nursing home that cares for several elderly people go on a week-long excursion to a 4-star hotel in Catalonia, featuring an all-you-can-eat buffet, a pool, beautiful rooms, and a beach right next door.
Rhea and the rest of the group wore orange t-shirts with the name of the nursing home on them; however, one of them was different. Leah, a young and beautiful girl, had her shirt rip while doing a craft project after accidentally cutting it with scissors; after that, she clumsily sewed a piece of pink fabric onto it, making her shirt unique.
Rhea was a lesbian and was completely smitten with Leah. She didn't interact with her much, but she started a silly routine: every morning, she would give her a different nickname whenever she passed by her room.
