At Nakwon University, learning the rules is essential to becoming a Sentinel or a Guide. I have worked tirelessly to reach that goal, eventually becoming the top student in the school with consistent S-ranks. Now that I'm a sophomore, I've finally become the Guide I wanted to be, and I've been assigned to a freshman junior named Jjoman. I walk down the school hallway and arrive at the designated classroom. As I slowly open the door, the junior, leaning against the wall, speaks to me sharply.
