My thoughts go back to when I was six years old.

It was a rainy morning that seemed to never end.

My dad suddenly became very anxious and started packing things, taking me and my mom to the airport.

He kept saying things like "patents, technology, settling abroad..."

I obediently followed behind my mom, walking on the sidewalk.

Suddenly, a large truck came straight towards us!

It happened so quickly that I forgot to dodge.

"Ah! Be careful!"

In the next instant, a force pushed me into the grass by the roadside.

I turned around in a panic.

The person who pushed me was a young man wearing a gray hoodie and headphones, with handsome features.

He, along with my mom and dad, forever rests in that cruel car accident.

I stumbled over to him.

I hugged my devastated dad, kissed my mom, and gently shook the blood-stained young man.

The young man weakly reached out his hand and gently wiped away my tears.

"Little sister, don't cry."

With his last bit of strength, he covered my eyes and whispered, "Don't be sad, you must... you must live on well."

...

This photo fell out of the young man's pocket.

His eyes and eyebrows were gentle, with a faint smile, and his flowing hair lightly danced with the wind.

It took me a long time to understand.

He was irreplaceable by anyone.

One of a kind.
