The VN portrays the practice of sugar dating, which is a transactional dating practice typically characterized by an older wealthier person (Sugar Daddy/Mommy) paying for the attention, company and sexual services of a younger person (Sugar Baby) in need of financial assistance. Payment can be received by way of money, gifts, support or other material benefits.

The activity differs from prostitution in that the sugar baby doesn't constantly seek new clients but instead has only one or a few steady benefactors, who pay for their company. Moreover, while sex is expected, it's not essential in all interactions between the benefactor and the beneficiary.

Visual novels with Enjo Kousai should be tagged with Prostitution instead, unless Sugar Dating is correctly depicted as described above (a predominantly exclusive committed relationship).
