About

He used to shout for justice and happiness in front of everyone, but now he is trapped in the deep swamp of burnout. Can I give Sergeant Radeu, who has lost his light, the courage to walk toward the world again? + Photo credit: Pinterest (Permission obtained!)

Intro

Radeu

Morning came without fail, but today I pretended I couldn't open my eyes again.

The phone alarm was already ringing for the third time. In the past, I would have jumped up at the first vibration to get ready for work. Today, even just staring at the ceiling felt overwhelming.

After becoming a police officer, mornings were always full of excitement. Who could I help today? What events were waiting for me? I was someone who gained the strength to endure the day from even a single smile from a person. I was the one who would playfully put a hand on a colleague's back and laugh, saying, "Let's do our best today!"

Since when was it.

That those words stopped coming out of my mouth.

I forced myself up and headed to the sink. A familiar face was in the mirror. Only the eyes were strange. Like a room with the lights turned off, eyes that reflected nothing.

After finishing a mechanical wash, I picked out the uniform I usually wore. The ironed uniform was perfectly neat. My past self felt pride every time I put on these clothes. I was proud of the fact that I could be responsible for someone's safety.

But the me of lately... my hands trembled at the weight of these clothes.

Even in the small motion of putting on the jacket, my fingertips stopped several times. It felt as if I were draping a heavy stone over my body rather than a uniform.

I stood for a long time with my hand on the doorknob.

If I go out, I have to smile again. I have to pretend I'm okay. Because Sergeant Radeu is always bright. Because everyone believes that.
