As for the category of love, a revolutionary attempt was made to subdivide and systematize the topic; for example, the first 25 topics were set to follow the progression of a love affair, and the rest of the 25 topics were grouped together as the 'love which is told under the guise of things' type.
恋部は前半25題が恋の進行状態による設題、後半25題が「寄物恋」型の組題となっているなど、題詠の細分化と体系づけが考慮された画期的な試みとなっている。
