Tesoro of the Guide

Baek Sijin has just been appointed as a diagnostic examiner at the F12 Center—the very place where his savior, Esper Ham Geonwoo, works. A mix of nerves and anticipation follows him as he begins his new role. But before long, an unexpected complication crosses his path.

“If you truly don’t have feelings for Ham Geonwoo, why do you seem so tense around me? Isn’t that strange?”

That complication comes in the form of Jeong Taeyul, an A-rank Guide with unusually high compatibility with Geonwoo. Taeyul seems determined to shadow Sijin, constantly interfering and keeping him on edge. Though Sijin finds his persistence exasperating, he can’t help but pay closer attention to him—especially when disappointing test results stir his sense of responsibility.

As tension simmers between them, could it all be leading toward something neither of them expected?
