With Summer! With Friends! With Launching Fireworks!

Harima continues submitting his love-fueled manga to publishers, with himself and Tenma as the leads. On his way home, he spots Eri—and panics at the thought of her discovering his secret hobby. As Harima flees, he's intercepted by Mikoto, who invites him to a café. But when Eri walks in and sees them together... misunderstandings explode like fireworks.
