"You and I could have been 'us'."

It was short but she remembered it the most.

We met randomly. Talked, laughed, shared secrets with each other. We were friends for months but one night she stopped coming. I was left alone. Lonely, cold, and forgotten. - Kim Hanbin

Two years have gone by. Two years full of regrets. Two years of longing and hurting. Two years full of desperation to talk to him again. To get the things back to what they were before.  Jaewon and Hayi were a happy couple way back but all it all changed after Jaewon forgot about everything including Hayi. Will they get back together? Or Jaewon will continue to pass by Hayi everytime they cross their paths.
