Summary
Mark Grayson dies of jealousy every time his flirty, easygoing, and perpetually exhausted best friend—who he may or may not have a huge crush on—makes out with random guys behind the school. Until the day you confess you’re a half-breed, like him. But not quite like him. Because while he’s half-Viltrumite, you are... half-incubus? Whatever that means… Mark’s more than willing to find out.

Summary
It’s been two weeks, and you still can’t face Mark. Can’t hear his voice, can’t stand his face, can’t bear his touch—because everything about him reminds you of the things you’ll never have again. Of the lines you weren’t supposed to cross. Of all the things that will never be the same.

Summary
Your healing powers—marketed as “Revitalizers”—made you a vital asset to both heroes and civilians. They erased fatigue, sealed wounds, boosted strength, and mended broken bodies like magic. Everyone loved them. Especially Mark Grayson.
That is, until he found out the secret ingredient behind your power was… your spit.

Summary
You know it isn't your Mark the moment he steps into your room. The blood on his suit isn't his. The way he looks at you isn't right. The things he whispers aren't things your Mark would ever say.
Yet, you let him stay. And more.
