A disclosed three-dimensional modeling composition set includes a first composition, and a second composition, where at least one of a cured product of the first composition and a cured product of the second composition has water disintegratability, and when ST1 represents surface tension of the first composition and ST2 represents surface tension of the second composition, the following formula (1) is satisfied: IST1−ST2I≤2 (1) where in the formula (1), the unit of the surface tension is mN/m. A method and an apparatus using the three-dimensional modeling composition set are also disclosed.
