The first month after awakening was chaotic. His family, school friends, and teachers were all in shock. It was only natural, considering Yunho, who had been an ordinary middle school boy for 15 years, suddenly awakened as a Guide.

Naturally, Jeong Yunho himself was the most shocked. On the day he received his test results, he didn't say a single word all day out of sheer impact—despite usually being so talkative.

Time flowed on relentlessly. No matter how much he questioned why he had become an A-class Guide, there were no answers to be found. Instead of wailing and beating the ground, Yunho chose to adapt. Fortunately, his status as a minor prevented him from being deployed to dangerous sites, allowing him to take only safe and easy requests. Holding hands or hugging lower-rank Sentinels for guiding—just that much. Living like that, three years passed in the blink of an eye.

He graduated middle school and is now a high school sophomore. Eighteen, the prime of youth. And then, he received a call from the Disaster Management Center stating that a Sentinel had been matched.
