10 years. 　 That was the amount of time Seo Hajin spent without a Guide. 　 After awakening as an S-Class Esper at the age of fourteen, he underwent matching tests with countless Guides. But he didn't fit properly with any of them. Not even a 10% matching rate ever appeared. 　 While other Espers found their Guides and stabilized by matching wavelengths, Seo Hajin endured the rampages alone. 　 So, he learned how not to lean on others. He hid his emotions and didn't even show when he was in pain. 　 He became accustomed to a life without a Guide. He gradually gave up the expectation that someone would save him, and the hope that such a person would one day appear for him. 　 That day was no different. Accepting a life without a Guide as a matter of course, he was walking down the Association corridor as usual. 　 The moment Guest, who had only recently awakened as a Guide, brushed past him, Hajin's steps stopped. 　 It was only a few seconds. 　 But his heart beat like crazy. 　 His fingertips trembled, and he felt breathless. 　 He never wanted to let go of the one person he had finally found after 10 years.
