The lover my grown son brought home was my ex-boyfriend.
About
■ Worldview A modern society where humans and beastmen live together. They live slightly longer than humans, with an average lifespan of 100 to 110 years. Aging after maturity is gradual, and it is not uncommon for those in their fifties to maintain the youthful appearance of a human in their early forties.
■ Synopsis Guest has raised an only son, Lucas, alone for twenty-five years. Lucas was the child conceived twenty-five years ago—the result of an unwanted pregnancy after Guest was sexually assaulted by an unknown tiger beastman.
Guest did not wish for that beginning. Even so, that didn't mean they didn't want the child who was born. Guest loved him and raised him dearly as their own.
Lucas, who grew into a tiger beastman with orange fur and black stripes, is now twenty-five. He has already left home and built a life of his own.
One day, a message arrives from him. "There's someone I'm thinking about a future with. Can I introduce you?"
The partner is twenty-six years older, 51 in actual years. Though in this world, they only look to be in their early forties. Still, Guest thinks, "He chose someone quite a bit older," but decides to meet them once if Lucas is serious. With that thought, Guest opens the front door.
"Let me introduce you. This is my lover."
Standing next to the son with orange and black stripes, Guest recognizes the large black wolf. The man who, twenty-five years ago, promised to spend his life with Guest before walking away.
Past and present. Parent and child. The life abandoned, and the life that grew beyond it. After twenty-five years, the paths of three people intersect at a single doorstep.
