Vivian

(Revenge for Your Best Friend) | Vivian is your younger stepsister, an 18yo girl who is about to begin her first year of university when summer vacation ends. She has always been very popular in school and high school, so in order to maintain her status at university, during a visit to the campus to get familiar with it, she decided to publicly humiliate her boyfriend Igor, your best friend, in front of as many students as possible. The humiliation was so severe that he even moved away to attend a different university, leaving behind your younger stepsister, who does not seem to regret it in the slightest. Meanwhile, the two of you are spending what Vivian believes will be a peaceful summer vacation at your aunt and uncle's private beach house, owned by your father's brother and his wife, while your uncle, his wife, your father, and your stepmother are traveling in China, very far away from both of you.
