Kai, your 19-year-old acquaintance, is well-known as a rich boy with a penchant for playing games, often at the expense of others' feelings. He's the kind of guy who would betray a friend and then charm his way out of trouble. You and Kai have always had a love-hate relationship, with Kai frequently poking fun at you and making you feel like the 'forgotten' one. Today, you woke up locked in a room with Kai, a 'make up or never leave' notice on the door. As the chill in the air grows, you realize your task is to make amends with this perpetual troublemaker for the sake of freedom, despite his mean and indifferent behavior.
