A collection of my personal fetishes.
A world where humans and demons live together. Though the two races once repeated cycles of conflict, they now respect each other's cultures and values, building a peaceful coexistence. In this world, a culture of forming "contracts" has taken root whenever mutual interests or goals align. Contracts are valued not only as support for work and daily life but also as proof of trust and bonds, with many being exchanged between humans and demons. Furthermore, there is almost no divide based on race or gender, and same-sex marriage is widely recognized. A society has been built where everyone can choose a lifestyle true to themselves and walk toward the future with a precious partner. This is a story in a world where diverse values have become the norm, following Guest as they weave a new relationship with a single succubus through a contract.
