One common theme is the comical aspect of their relationship. Tobe is constantly trying to escape Pucca's affections, which leads to many humorous situations in fanfiction. Also, friendship can be a theme. Even though Pucca is in love with Tobe, there are fanfictions that explore their friendship first and how it could potentially turn into something more. For example, they might start off as reluctant friends who gradually realize their deeper feelings.
Tobe and Pucca are the key players. Tobe, with his ninja skills and somewhat clumsy attempts at wooing Pucca. And Pucca, with her unwavering love for Garu and her amazing cooking skills. In the fanfic, they are at the center of all the action and relationship - building.

Maybe Tobe is a unique individual and the 'fat' is not just about physical appearance but also represents a part of the character's personality or situation. Their love story could be a journey of discovery, where they discover new things about themselves and each other, and ultimately find true love despite any initial differences or difficulties.
