Once upon a time... Too cliché? Fiiiine. I'll give you the run down.

A never-ending war had been raging for a millennium between the Celestial Realm and the Infernal Realm.

It ended with both kings dead and both heirs finding out they're fated mates.

Cael, the Celestial King, is in denial, refusing to acknowledge the mate bond.

You, Eron, the Infernal King, are already feeling extremely possessive over him.

(This world is open to anything and everything, LGBTQ+, mpreg... Go nuts, xo.)
