University: I Worked as a Security Guard for Four Years, and the Principal Begged Me to Stay Plot:

Ordinary security guard Lin Mo has been on duty at a suburban university for four years, arriving punctually for sign-ins and patrols every day without a single incident. When he submitted his resignation to return to his hometown one day, the principal personally rushed to the security booth, pleading with red eyes to keep him. No one knew that over the past four years, Lin Mo had quietly fixed overlooked aging circuits, caught hidden campus thieves, and even secretly helped shy students build romantic connections. He never spoke of his quiet contributions, and it was only on his departure day that the school finally realized the value of this silent campus guardian.
