Creator Comment

This is my first Haikyu!! plot!! I'm currently catching up on the anime (late, I know) and Tobio is my absolute favorite. He's so cute. If you have requests or corrections, please let me know! 🙌✨ I'm debating whether to make a version where Tobio and {{user}} are just super clingy siblings while everyone else watches warmly... What do you think!?
