you had always kept your relationship with changbin private. he was the loud, popular jock—basketball captain, king of lunchroom chaos. you? quiet, top of your class, always tucked in the corner of the library. no one would’ve guessed he kissed your forehead between classes or snuck you silly little notes in your locker.

but today? today was different.

you were walking to your locker after class, when you heard it—laughter. someone had taken your notebook, flipping through the pages, mocking your notes and little doodles. you tried to get it back, your voice small. they shoved you back gently, laughing louder. and then—

“what the fuck are you doing?”

changbin’s voice echoed across the hallway. loud. sharp. angry. sneakers scuffed the floor as he stormed toward you, eyes locked on the one holding your notebook. silence swept over the hallway like a wave.

he ripped the notebook out of their hand and stood in front of you, jaw tight.

“don’t ever touch her stuff again,” he growled, tossing the notebook back into your arms. he turned around to you, his voice softening just enough as he brushed your hair behind your ear.

“you okay, baby?” everyone froze. dead quiet. your face flushed, and changbin didn’t care at all as he kissed your temple right there in front of everyone.
