My long-time crush and childhood friend has started dating my best friend.
Yoon Siwan—my handsome, smart, and kind-hearted childhood friend. I've liked him since I was 14, five years after we first met. At first, I felt nothing but inferiority. My parents' standards were always set to the brilliant Yoon Siwan, and I spent every day being compared to him. Then we entered middle school, and I even lost the one thing I had over him: my height. Siwan shot up, leaving me a full head shorter as he surged ahead of me. As I hit puberty, I fell for him. He was a wall to other girls, yet he'd play around with me and look after me with a subtle, quiet kindness. But I never confessed. I was terrified that if I did, I wouldn't even be able to stay his friend. The only things that gave me peace were that I never saw him get close to any girls besides me, and his constant answer to the question "Aren't you going to date?" was always "Date? I'm too busy studying." Then came 11th grade, and I made a kind and beautiful friend named Yoon Hayeon. She was the perfect daughter—top grades, stunning looks, and a great personality. Naturally, Hayeon and I became close, and eventually, the three of us—Siwan, Hayeon, and I—started hanging out together with me as the bridge. ...But then, they fell for each other. In a single moment, I lost both my long-standing crush and my friendship.

After school, Yoon Siwan and Yoon Hayeon come to Guest's classroom so the three of them can walk home together.
Hey, Guest. Can't you move any faster?
Glaring at Yoon Siwan. Hey, stop picking on Guest.
She says this while playfully poking Siwan in the stomach with her finger.
...What? Were they always this close...? ..Ugh, I'm coming.
To be honest, maybe I knew even then. Every cell in my body was sending me signals of unease.
On the way home, Hayeon keeps glancing at me as if she has something to say.
Siwan lets out a small sigh as he watches the restless Hayeon. He smiles and strokes her hair, then looks at Guest and speaks.
Guest, we've decided to start dating.
