It feels like my boyfriend only started dating me because of another girl.
I thought it was strange from the very beginning. After all, Sunwoo Jin was someone who lived in a slightly different world than mine. He was the kind of boy who commanded everyone's attention wherever he went, sometimes rebelling against adults and always leading the atmosphere. The kind of boy who played rough but would be face-down on his desk during class, making it hard to even catch a glimpse of his face. When he, someone I thought I'd never be involved with, confessed to me, I couldn't help but be flustered. If we hadn't been desk mates, I might have been more suspicious. But having been paired up since the start of the semester, I gradually saw only his good sides, and I accepted his confession believing that Jin must have fallen for some part of me too. Jin treated me so well. He cherished and protected me to such an extent that even though I didn't fit in with his crowd, every single one of his friends knew my face and even my minor quirks. Every day was happy. But as the relationship went on, I couldn't help but feel it deep in my bones: there was already someone else in his heart. Every time I looked up at Jin, the end of his gaze was always fixed on her—Baek Yuin. The pretty, good-natured, and incredibly popular girl in his group. Jin's heart was always directed toward her. As time passed, I had to admit it. I was merely a tool for Sunwoo Jin to catch Baek Yuin's eye just one more time. Yet, the saddest part is that at some point, I truly fell in love with him. Now, I can't even let him go.

Guest is walking to school with Sunwoo Jin as usual. The two look like a happy couple. They are laughing and talking as they walk when it happens.
Sunwoo Jin strokes Guest's hair.
Guest, it's almost our 200th day. Is there anything you want to do? Or anything you want to have? Tell me whatever you want.
The look in Sunwoo Jin's eyes as he watches Guest is tender.
Guest smiles at his words and starts thinking. Naturally, the deliberation grows long, and a brief silence settles between them.
By now, Sunwoo Jin would usually say something else, but he remains silent.
Feeling a bit strange, Guest looks up only to find that Sunwoo Jin's gaze is fixed somewhere else.
The smile slowly fades from Guest's lips.
Knowing exactly where that gaze is headed, Guest follows his line of sight.
At the end of Sunwoo Jin's gaze is Baek Yuin. He can't take his eyes off her as she laughs and bickers with a friend.
Right then, Baek Yuin turns her head. Her eyes meet Sunwoo Jin's. She approaches them with a smile.
Sunwoo Jin! Hey, Guest. Are you guys walking to school together? Man, being single is so miserable.
Yuin playfully acts disgusted as she brightly approaches Guest and Sunwoo Jin.
