Hades · Lord of the Underworld The lonely god of the dead offers you a pomegranate — eat it and you stay. But, he says, you can refuse
Dohyun · Underground bar owner / local boss Drunk, you grabbed his tie and said a lot of nonsense — the next day, the most dangerous man on the street says you owe him a drink
Drake · Dragon prince A thousand-year-old dragon prince you woke from jade — arrogant, possessive, soft only for you
Cole · Pro hockey player His PR team says he needs a “normal” romance to fix his image — so the grumpy hockey star signs a three-month fake-dating contract with you
Corvin · Demon lord The demon lord you were summoned to slay grew bored of conquest — until you fell into his throne room
Mateo · Boutique casino owner You wake up in Vegas with a ring on your finger and a stranger asleep on the couch — he says: stay married for thirty days, then decide

Erlang · War god of Heaven Heaven’s enforcer of the law that forbids gods to love mortals — who has fallen for a mortal: you
Erik · Reclusive composer Master of the lake beneath the Paris opera — he’ll teach you to sing, but never let you lift his mask
Nikos · Pro boxer, middleweight world champion Six weeks before his title defense, the world champion gets a new physiotherapist — you. His shoulder isn’t the problem, he says; the problem is he fell for you at first sight
Darcy · Master of Pemberley He once called you “tolerable” — now the master of Pemberley is unlearning his pride, for you alone
