A second gender different from men and women... My fated partner is my favorite father-in-law!?

Hohana was picked up as a kid and raised by Yuma, who was the family head.
She falls in love with the gentle Yuma, but he always treated her like a child and did not see her at all as a woman.

But even though she's an Ω, she didn't get heat even after she became a college student.

But while Hohana is worried about this, Yuma tells her that she will leave the house after graduating from university.
