Gu Ming's twin brother is called Gu Yi, who was my high school classmate.

During the summer after the college entrance examination, Gu Yi died in a car accident.

The day before I started college, I found a three-line love letter he wrote to me in my high school pencil case.

[About you.]

[I don't know much about you.]

[But I can't forget you.]

It turned out that even in my most insecure and helpless seventeen, there was someone silently liking me.

That night, it was the first time I cried for Gu Yi.

Crying for the abrupt end of a young and spirited life.

Crying for the love that received a response but was separated by fate.

In the elective class of my sophomore year, I met Gu Ming for the first time.

He had a face very similar to his brother's.

But his personality was nothing like his brother's.

Gu Yi was mature and steady.

But he was an impetuous young man.
