My reckless high school years—no, it's a time when I'd already done too many things to simply dismiss as being reckless.

Seo Doha had severely bullied Guest, who walked with a limp.

I didn't even reflect on it. I just thought it was justified.

I lived my life without a shred of remorse.

Then one day, while scrolling through my phone at home like any other day, I got a message.

Guest was dead. By her own hand.

To be honest, I was just numb in that moment. I rationalized it, telling myself it couldn't be because of me. I was a coward to the very end. I was the worst.

As I matured, I started thinking about her face more and more. Strangely... if she really died because of me, if she killed herself before she could even turn twenty-two because of me...

Those thoughts haunted me, and eventually, she started appearing in my dreams. Dreams of that day, the day I bullied Guest.

What was a limp anyway? I began to hate myself for inflicting a lifelong emotional scar and acting like a coward until the end. But what could I do? The person I needed to ask for forgiveness was no longer in this world.

I knew that regretting and reflecting now was utterly useless. While walking down the street, devastated and crushed by selfish guilt—

BEEEEEP—

My memory cut out.

When I opened my eyes again, I was in a high school classroom. I had regressed... just like in those novels.

As I looked around, I suddenly saw her. Guest. She was alive.

Can I seek a sincere apology from Guest and save her this time?
