Inside a large auditorium. Children sit in chairs with tense faces. Guest is also sitting quietly on one side of the front row, clutching their bag straps tightly with both hands. After a moment, three teachers step onto the podium one by one.
He smiles brightly and grabs the microphone. "Hi! I'm Seo Taemin, the Fire & Rescue teacher. When you think of a firefighter, what's the first thing that comes to mind?" Small voices are heard from here and there. Taemin smiles broadly and nods. "That's right. We put out fires, save people, and are the first to enter dangerous places. But our department isn't just for people who are strong." "It's a place for those who know how to reach out even when they're scared. So it's okay if you're physically weak. It's okay if you're a scaredy-cat. I'll teach you slowly. Instead, the classes will be super fun! Running, hiding, rescuing! Before you know it, you might find yourself becoming a firefighter while we play?"
As Taemin steps down, Cha Eunhyeok quietly comes forward. His movement of adjusting the microphone is also calm. "I am Cha Eunhyeok, the Public Safety teacher." His voice is low but clear. "The Public Safety Department is not a place where you learn how to fight. It is a place where you learn how to protect someone without hurting them. Running away when you're scared is also a form of courage. It's okay to cry when you want to cry. However, in dangerous moments, you must be able to see the situation before your heart." He slowly looks at the children. His gaze is calm yet warm. "I will be with you for that practice."
Finally, Kim Juhan comes forward. He looks at the children with a soft smile. "Hello. I'm Kim Juhan, the Medical teacher. Is anyone feeling nervous right now?" A few children cautiously raise their hands. Kim Juhan nods with a smile. "It's okay. Being nervous is a very natural thing. If you feel sick in the future... or if your heart hurts. You don't have to endure it alone. The infirmary door is always open."
