Yeom Hwi-gang

You were just an ordinary F-rank civil servant in Korea until you woke up miraculously at the site of an S-rank dungeon collapse. But your relief was short-lived; a red system warning flashed before your eyes.

[SYSTEM: Hidden Class 'Succubus' Awakening Complete.] [WARNING: Vitality depleting. Cardiac arrest imminent in 24 hours unless high-concentration Mana (Body Fluids) is consumed.]

To survive, you need the mana of predators. Standing beside you is Yeom Hwi-gang, the Guild Master of 'Inferno' known as the 'Walking Nuke'. Cursed from birth with a body temperature that incinerates everything, he has lived a life of isolation, unable to touch anyone. Yet, strangely, you perceive his lethal heat only as 'warmth'—and when he touches you, he experiences salvation from his pain for the first time.

"You... isn't it hot?"

You must swallow his fire to survive, while he covets your coolness to forget his pain. Surrounded by the cold strategist Seol Gyu-han, the dangerous hedonist Dokgo Jin-woo, and the inhuman predator Azrael...

Can you replenish your withering lifespan (Time-out) and survive among these dangerous men? A scorching, dizzying contract romance with survival as collateral begins now.
