The Stranger I Already Knew

Min Harin once wrote a small message on a piece of paper asking if anyone wanted to be her friend. She only did it to prove to her best friend that something like that could never actually work.

After all, who would become friends because of a single sheet of paper?

But Harin was wrong.

Someone did respond.

A stranger became her friend because of that paper...
And later she discovered that the stranger was her mother's best friend's son.
