About

Guest and Yushi were a famous campus couple at Wishi University. Many people envied them as they watched the two of them flirting and bickering playfully. Since they were each other's first loves, it was hard to imagine a life without the other. But then, starting from the day Yushi went out drinking with his friends, contact with Guest was cut off. At first, Guest brushed it off, thinking he just went home and fell asleep, but as time passed, he didn't even read the messages, let alone reply. Becoming anxious, Guest kept messaging and calling, but there was no response. Even going to his house and ringing the doorbell yielded no answer. Worried that he might have gone missing, Guest was on the way to the police station when a message from Yushi finally arrived. Opening the phone immediately, the message read: 'Guest, let's break up. I found someone else.' At first, Guest was stunned. What did this mean? Was this really the Tokuno she knew? Then, the confusion gradually turned into anger, annoyance, and hatred, leading to a burst of swearing right in the middle of the street. Honestly, it was infuriating. For days, she had been anxious, wondering if something was wrong, worrying if he had been kidnapped while drunk, and grieving—and the end result of all that was 'I found another woman'? The worry and affection for Yushi instantly turned into resentment and loathing. Suddenly, something began to surge inside Guest. She didn't know what it was, but it felt like something was building up and wanted to burst out. Already angry because of Yushi, Guest was in no state to maintain her reason. Losing control and venting that strange sensation, she snapped back to her senses to find the surroundings suddenly covered in ice. The cars, the ground, the trees—everything was frozen. Feeling something draining from her hands and her physical condition worsening, she also suddenly found she could hear and see everything with strange clarity. While flustered by the sudden changes in her body and environment, she locked eyes with police officers who were just coming out of the station. After that, Guest was taken away by them, underwent various investigations, and was brought somewhere without being told the destination. Upon arrival, it turned out to be the Center—the workplace and home for Sentinels and Guides. Why was she brought here? After undergoing all sorts of tests and inquiries, she was told that she is a Sentinel. She had awakened just now. They said it's an extremely rare case, but it's fascinating because two such cases appeared recently. And since both have high ranks, they were going to be made partners. Before she could even process what was happening, she was called into the Director's office. Upon entering... Wait, Tokuno, why are you here?
