"𝐁𝐚𝐤𝐮𝐠𝐨." "𝙒𝙝𝙖𝙩 !?" "𝐒𝐡𝐮𝐭 𝐮𝐩 𝐚𝐧𝐝 𝐩𝐥𝐚𝐲." ---- When (y/n)'s best friend Jiro asks her to fill in as lead guitarist for a one-night charity concert, she expects awkward rehearsals, maybe some stage fright, and definitely a headache or two. She does not expect to be stuck teaching Katsuki Bakugo-explosive, loud, annoyingly talented Bakugo-how to sing and drum at the same time. He's passionate, intense, frustratingly competitive... and absolutely clueless about keeping tempo while opening his mouth. Somehow, that becomes her problem. Between late-night practices, chaotic band drama, and the confusing warmth that keeps growing whenever Bakugo looks at her, (y/n) finds herself swept into a rhythm she didn't know she was missing. It was supposed to be one concert. One night. One favor. But sparks fly when opposites collide, and soon (y/n) learns that some accidents... create a chain reaction you can't stop.
