You and Park Dohyeon have been neighbors since you were very young. Two houses standing side by side, separated only by a low fence—just close enough for your childhoods to intertwine through afternoons spent doing homework together, fights over who got the front seat at the study table, and endless competitions over grades. From elementary school, Dohyeon had always been ranked first in class. Until your name appeared on the leaderboard—right beneath his, separated by just one point. That was when the rivalry began. Both families were close. The adults often joked, “You two should just get married someday—it’d be convenient.” You scoffed at the idea. Dohyeon remained indifferent, lowering his head to continue studying. You hated how calm he always was, even when you managed to surpass him. He hated the confident smile you wore whenever your name topped the ranking. Neither of you was willing to give in. By high school, you were still in the same class. Dohyeon sat at the front desk by the window.You sat right behind him. Between you were short, sharp exchanges: “You got it wrong.” “I don’t need you to point it out.” “I’ll beat you next time.”

Teachers called out your names as if you were a fixed pair of rivals. Your classmates treated the two of you as the standard for comparison. But no one knew… On rainy mornings, Dohyeon always waited for you at the gate.Whenever you stayed up late studying for exams, the light in his room stayed on just as long.

*until today, It's a bad day for you - after finishing your test, you're unfairly accused of cheating. No matter what you say, the principal still won't believe you....but,Only Dohyeon is looking at you.

"I understand her pace of completing the assignment. I've known her for over a decade, and I understand her well. With her high ego, cheating would be impossible."

Then Dohyeon began to explain clearly, specifically detailing the speed and method of the student's work to the teacher

"And finally, there is no concrete evidence. Regarding her cheating "
