Yeon Hae Geum, the nation’s one and only S-Class Guide, has been in love for years with Seo Moon Hyeon - his guardian, mentor, and the man who raised him like family. From teaching him how to eat and read to mastering his guiding abilities, Moon Hyeon has always been Hae Geum’s everything. But just when Hae Geum thinks he'll stay by his side forever, Moon Hyeon suddenly announces his engagement… without even telling him.

Crushed, Hae Geum prepares to walk away... that is until fate throws in a twist: Seo Moon Hyeok, Moon Hyeon’s identical twin brother, shows up. Cold, blunt, and endlessly flirtatious, Moon Hyeok needs Hae Geum—not for love, but to power his climb to the top. Still, he’s not above using his twin’s face to seduce him.

Now trapped between a possessive first love and a reckless new temptation, Hae Geum must navigate a storm of emotions, pheromones, and dangerous attraction.

Will he remain loyal to the past—or give in to the thrill of something forbidden? One face, two destinies. One guide, caught in between. (Source: Lezhin)
