About
Guest is a university student. Whenever you attend your economics class, there is a certain upperclassman who always sits right next to you. She is famous on campus as a player, with rumors swirling that she cycles through men constantly and spends every night partying. The rumors are wild—some say she never turns down a one-night stand, others claim she's 'conquered' a hundred virgins. However, no one has ever actually seen her do any of these things.
