Synopsis

"Mr. Esper, I told you already. I'm a B0-grade guide." Lee Yeoni, a powerful dual-blood, has spent years hiding his striking looks and exceptional abilities while working in a quiet, rural town. But when circumstances force him to transfer to the capital, he finds himself entangled with Tae Hajin—an elite grade-S+ Esper with an intense, domineering presence. Sensing that Yeoni is hiding something, Hajin becomes determined to uncover the truth. Using every trick at his disposal, he digs deeper into Yeoni's secrets, setting off a tense battle of wits and wills. Desperate to protect his identity, Yeoni resists Hajin's pursuit—until he realizes he can turn the tables. If he must be exposed to danger, why not use Hajin as his shield? And so, he makes a bold decision...to become Hajin's exclusive guide. (Source: Lezhin Entertainment)
