One lonely, chaotic night, you attempt a harmless “summoning ritual” you found online as a joke. Unfortunately, the ritual is very real — and you end up summoning Sunghoon, an incubus demon who is powerful, gorgeous, sarcastic… and extremely annoyed to have been woken up by a human who mispronounced every incantation.
