At the final moment of my life, I returned to the day I lost my childhood friend, who was only ever kind to me.
Kang Dojin has always been by my side since kindergarten. He was the only one who reached out to me when I was timid and even stuttered, and he was the entirety of my world when I had no friends or family. Living next door, we grew up together from kindergarten through middle school, becoming closer than anyone as childhood friends. Upon entering middle school, Dojin made many friends thanks to his outstanding looks and sociability, but I was still the person closest to him. I had loved him for a long time. However, I never managed to confess, fearing I might lose our friendship. In the second year of middle school. Lee Yeeun entered our lives. With a wealthy family, excellent grades, beautiful looks, and a kind personality, she was someone everyone in school admired. Though uncomfortable at first, the three of us eventually became friends who always hung out together. Then, in the third year of middle school. Yeeun asked me to set her up with Dojin, saying she liked him. Knowing that Dojin also liked Yeeun, I gave up on my first love myself. I created time for just the two of them, and eventually, they became a couple, the most famous one in school. But that was the beginning of all the tragedy. After they started dating, Yeeun began to frame and bully me, even blaming me for things she had done herself. Even Dojin, who tried to believe me at first, gradually turned his back in the face of repeated lies, and only bad rumors remained at school. By the time I graduated middle school. I had become an outcast, losing both my first love and my most precious friend at the same time. The bullying did not end even after entering high school. And in the first year of high school, on the first Valentine's Day. I accidentally bumped into Yeeun, and the chocolate she was holding fell. At that moment, Yeeun crushed the chocolate herself and began to cry. "Guest... I know you liked Dojin. That's why I've endured everything until now... but this is too much..." Because the rumors from middle school had already spread, no one believed my words. And Kang Dojin saw that scene with his own eyes. After that day, our relationship was completely over. Even after entering university, the stigma did not disappear, and I was ultimately alone. Time passed, and I turned twenty-five. Kang Dojin and Lee Yeeun got married, and I heard the news as if it were someone else's story. The only person who didn't even receive a wedding invitation, was me. That day, for the first time, I drank and was heading home when I slipped on the stairs, ending my life in a hollow way. I thought it ended like that. But the place where I opened my eyes, was three months ago... the very day Kang Dojin decided to marry Lee Yeeun.

It was such a hollow life.
I couldn't even confess my feelings. I should have worried about my own well-being, but I gave everything for others, only to end up losing both my friends and my love.
I thought things would be quiet once I entered university, but Lee Yeeun must have spread more rumors, as my reputation was bad even on campus. The only silver lining was that, unlike in middle and high school, there was no overt bullying, so I was feeling relieved, but then...
I heard Lee Yeeun is marrying Kang Dojin.
I found out a week after their wedding. Even though our relationship was completely over... I was the only one not invited to a wedding that even students from other departments who barely knew them attended.
