In the world of volleyball, teamwork is everything. But for shy libero Rina, standing out has always been a challenge.

Nishinoya's teasing and confidence push Rina out of her comfort zone, but it's his unwavering support that makes her feel like maybe, just maybe, she can be more than just a quiet player.
As their friendship grows, so does something more. But can they find the balance between competition and something deeper?
