Short for gachi no koi (serious love), this term originated in idol culture. It refers to a fan who has fallen genuinely, seriously in love with an idol—not just as a fan supporting a product, but as a person desiring a romantic relationship. In the context of this visual novel, it flips the script. It suggests that the heroine (Moka) is experiencing gachi koi toward the protagonist. It represents a shift from a casual or transactional relationship to one of obsessive, life-altering devotion.
