Hina puts her plan to move out into motion. Neither Rui nor Natsuo wants her to leave, albeit for different reasons. Will their home feel the same without Hina in it?

Natsuo takes a tumble down a flight of stairs, but a broken leg is the least of his worries when he's caught in a lie by Rui.

Rui makes a decision after her conversation with Natsuo. Later, Natsuo's class takes a field trip to Okinawa, where feelings are laid bare beneath the light of fireworks.

When the unthinkable happens, Hina expresses her love for Natsuo the only way she can: by giving him a chance to move on.
