Seok Kangwoo, an Esper addicted to illegal guiding drugs.

Tormented by constant pain without a matched Guide, he becomes obsessed with guiding drugs.

While fleeing after stealing drugs at a club, Kangwoo is caught red-handed by Kwon Jihan, a detective from the Illegal Guiding Drug Task Force.

In that moment, the two realize they’re a highly compatible Esper–Guide pair…

Jihan, who lives by the book, can’t understand Kangwoo’s insistence on self-destruction. And Kangwoo finds Jihan’s moral high ground nothing but infuriating.

“If you want guiding from me, quit the drugs. I won’t tolerate drug trafficking in the zone I’m assigned to.”

“I’ll take care of my own condition. Even if I drop dead, don’t expect me to call you. So stay out of it.”

Thus begins the strange cohabitation of the somewhat overbearing but principled Jihan, and Kangwoo, who can’t help but stir up trouble at every turn.
