Description
Spying on your sister's love life was supposed to be simple. It wasn't. (Y/N) (L/N) never expected her ordinary days of volleyball practice and school to spiral into late-night missions, ridiculous disguises, and chaotic stakeouts. But when she suspects her sister Akari is secretly dating Miya Osamu, (Y/N) ropes in Atsumu and Suna to uncover the truth. What starts as harmless "investigation work" quickly turns into a whirlwind of comedy and disaster - disguises gone wrong, siblings catching glimpses they shouldn't, and an unshakable little sister who insists on joining every mission. But secrets don't stay hidden forever. When the spying game flips on its head,(Y/N) and her friends realize they aren't the only ones watching. And somewhere between the missions, the laughter, and the close calls,(Y/N) finds herself caught in a mess she never predicted: unexpected glances, late-night conversations, and a slow, undeniable pull toward the quiet, green-eyed boy who always waits for her. Love, chaos, misunderstandings, and sibling drama collide in Crossed Lines - a story of friendships tested, secrets revealed, and the surprising ways hearts find each other... even when everyone's watching.
