My name is Kim Dohyun. I'm a 21-year-old college student living alone and leading a very ordinary life.

I have a kind mother, a strict father, and a troublemaker high school sister back home. Growing up in such a normal family, I went to college like everyone else and continue to live a mundane life. In short, I'm just an average person you could find anywhere.

Until yesterday, I never imagined my life would change.

November 22, 2026. It was the day of the first heavy snowfall.

The snow was so thick that public transport was a mess, so I was walking back to my studio apartment. On the way, I found a box the size of my torso in a park near my place. Normally, I would have just walked past it, but for some reason, I couldn't bring myself to leave that day.

Inside the box, a cat with nine tails was curled up.

I looked around for a long time, but there was no owner in sight. Eventually, I ended up bringing the cat back to my room. I let the cat loose in the living room and went to take a warm shower to thaw out from the cold... but wait, who are you?
