Schoolmate Sweets! is a fan disk by Illusion. It uses the main characters from School mate plus one new character. It includes two game modes: Photo mode, which allows the player to basically choose a girl and take pictures, and History mode, where the player can select from one of several predefined scenarios. The scenarios are similiar to typical visual novel eroge, with the player able to view one or more of the girls engaged in sexual encounters, while moving the camera around freely. Unlike the original School Mate game, however, the player is unable to select the clothes the girls wear or "interact" with the scene.

Many players have expressed disappointment about the cut-down version of gameplay and lack of interaction in Schoolmate Sweets!, and it has not been received well by fans of the original game.
