Succubus Lulu, who survives by taking a man’s essence and changing partners every day, is doing what he always does—taking care of his “meal” in a back alley. But this time, she gets caught in the act by Dongwook, who unexpectedly helps him out. Smitten by his kindness, Lulu starts following him around, insisting that if he wants to keep living in the human world, he’ll need his essence to survive.

A cohabitation story between Lulu, the cute and clueless succubus, and Dongwook, the diligent and upright young man of this era.♡
