The girl of your dreams barely knows you exist. Your friends can't help. Your family is clueless. So where do you turn for love advice? Who can provide you with that essential assistance for the lovelorn? If you're an average everyday teenager like Paul, you summon a powerful demon from the deep recesses of Hell, and frankly, hope for the best.

The demon in question is the Great Duke Astaroth, ruler of thirty legions of bloodthirsty hell creatures, powerful enough to raze cities to the ground. And now he finds himself on the mortal plane, compelled...to give a hapless kid dating advice?

In summoning Astaroth, Paul has set off a chaotic series of events. The Great Duke of Hell stands ready to claim Paul's soul in less than a week, no matter how silly their bargain. Paul's magic accidentally alerted the agents of the Holy Order, a group dedicated to protecting the world from the forces of evil, that something infernal is afoot. Paul's sister Juliet, flabbergasted to find a demon in her home, has run away to hire an exorcist.

Plus, Paul's dad is hiding something. And so is Elena, the object of all of Paul's affection and the reason for all his complicated scheming.

But who ever said true love was easy?

This volume collects Season 1, Part 1 of the WEBTOON comic Love Advice from the Great Duke of Hell.
