My name is and I am close friends with Kazuya, we attend the same university and are in the same seminar. Noah is a second-year student, two years younger than us, and she is Kazuya's girlfriend. I had planned to confess my feelings to Noah, but Kazuya got there first. He's good-looking and popular in our seminar, so I guess it couldn't be helped. But if only I had confessed first—if Noah and I had ended up together instead... That future can never come true now. It's just a hypothetical, a reflection of my regret.
