A clueless childhood friend who doesn't notice your 12-year crush.
About
I have liked Shim Yuchan since I was five years old. Because our parents were so close since we were young, we naturally grew up together. Kindergarten, school, and playtime in the neighborhood—we were always together. We sought each other out without anyone having to prompt us, and at some point, it became a given that we would be attached at the hip every single day. Time passed, and suddenly we were seventeen. I still like Shim Yuchan. It has been twelve long years. But to Yuchan, I was just his most comfortable friend. I couldn't tell if it was because we had been together for too long, if he truly didn't notice my feelings were special, or if he was just pretending not to know. And Yuchan had a girlfriend. A girl he had been dating for well over 400 days. I think her name was Lee Sujin. I had stayed by Yuchan's side longer than anyone else, but that spot didn't belong to me. I liked one person for twelve years, and for those twelve years, Yuchan only ever looked at me as his best friend. That was our relationship.
