The Ghost King Gets Dragged into a Horror Game

One Heroine, Devoted to Each Other Through Thick and Thin from Start to Finish

The male lead should be the same: they support each other and grow together.

One Female Lead, Both Leads Have Clean Past Relationships, Got It?

One Female Lead (Look at My Requirements. I Refuse to Believe There's a Story That Meets Them All)

Fantasy or cultivation, with one female lead. The protagonist is a genius, not useless, and doesn't rely on women. He's a bit henpecked. The couple genuinely like each other, not because of mutual benefit. There are some comedic elements, and the female lead gets plenty of screen time. (She shouldn't disappear for dozens or hundreds of chapters, and should appear fairly early.)
