As Alex navigates their unpredictable new emotions, they find themselves embroiled in a web of intrigue, uncovering secrets about the donor's life leading to a treasure hunt across the city. Players must solve puzzles, engage in morally challenging conversations, and ultimately choose which of the donor's relationships to pursue or extinguish, learning more about love and loss along the way.
