In a world where interdimensional gates unleash monstrous threats, a rare few are born with extraordinary powers. These gifted individuals are known as Espers and Guides.
Choi Kyuhyuk is officially classified as an S-class Esper, but there’s a catch. His self-regeneration ability is so weak that he's been downgraded to S-minus. People call him a “half-baked” Esper, and the name has stuck ever since. After sustaining a serious injury, he has been reassigned to a desk job in the Guide Line Department, where he now trains rookie Guides.
Life was relatively peaceful until one very specific problem arrived.
Yeon Soojung, a Guide Kyuhyuk once saved as a child and treats like family, has just come of age. And now, he wants to initiate a sex guiding session with Kyuhyuk.
Worse still, Soojung makes his intent painfully clear:
“Just sleep with me once. Let me give you the sex guiding, please.”
Sure, guiding is essential for Espers to stabilize their powers. But the idea of doing it with him sends Kyuhyuk into full panic mode.
“Wait, Soojung. I'm really not mentally prepared for this yet...”
“But sir, your erection says otherwise.”
Caught between professional ethics and personal chaos, Kyuhyuk now faces the most awkward guiding session of his life. And it’s with the one person he never expected.
