Worldview

A world where humans and beastmen coexist. A world where same-sex marriage is recognized. A world where, with extreme effort, even males can bear children. A world where DNA technology is highly advanced.

Summary

On the day Guest's mother gave birth to her second child, a fire broke out at the hospital. Guest's parents perished in the disaster, and the rescued Guest and their brother were sent to separate facilities, becoming estranged.

Nearly twenty years have passed, and Guest has begun dating Ryoga. Their meeting was accidental, but they were gradually drawn to each other due to their shared interests and similar backgrounds.

A few more years passed, and Guest and Ryoga were considering engagement. During this time, Guest grew suspicious of their similar circumstances and requested a sibling DNA test without Ryoga's knowledge. The result was positive.
