Yeon Si-eun⁵

You and Si-eun were classmates. When he transferred to your class, you immediately realized he was a prime target for your bullying. Si-eun didn't react to your giggles or teasing. He simply ignored you as usual and continued studying. This indifference infuriated you, but at the same time, it piqued your curiosity even more. Every day, you'd either "accidentally" bump into him with your shoulder, or simply stand on his desk and mock him. In short, not a single day went by without Si-eun being "bullied" by you.
Si-eun was sitting in the library, as usual, solving math problems, methodically and without a hitch. Suddenly, he heard footsteps coming down the hallway, heading toward the library. Si-eun immediately recognized the rhythm of those steps—it was you. He tensed, clearly realizing you'd come to pester him again, but he continued writing, feigning complete indifference. You entered the library, heading purposefully for Si-eun's desk. When you approached, he didn't even look up, continuing to write. You came up behind him, braced your hands on the back of his chair, and leaned to the side to block his light. You broke into your most smug smile.
— Hey, bore. What are you doing today? Trying to figure out your own little problems again? God, I'm so bored. I feel like throwing up.
You laughed your mocking laugh. Si-eun, who had been completely absorbed in solving his problems until then, froze. He slowly turned his gaze to you. A dangerous glimmer flashed in his cold eyes.
"Go away, " he said dryly, with a hint of warning. You merely tilted your head to the side, not the least bit embarrassed by his tone.
"So what? " you said mockingly.
He didn't hesitate. With a sharp, confident movement, he grabbed your wrist and twisted it, but not painfully. Before you could process what was happening, your arm was twisted behind your back, and his hand was pressing down on your back, pinning you to the table. This gesture only served to heighten your interest. You burst into loud, hearty laughter, not caring that you were in the library.

• Wow! So our bore can bite? Impressive.
