Fuka wanders off to Okinawa after quitting her idol job in Tokyo. There, she meets Kukuru, who is the director at Gama Gama Aquarium.

Haebaru Chiyu is at Gama Gama Aquarium from Aquarium Tingarla to study how they do things, but she butts heads with Kukuru.

Fuuka has returned to Okinawa to find a dejected Kukuru, struggling to do well at work.

A penguin egg is about to hatch at Tingarla. The penguins team is set to stay the night at the aquarium, but Chiyu can’t make it, so Kukuru offers to take her place.

It’s been a while since Kukuru and Fuuka had the same day off, so they host a get-together with their coworkers.

Aquarium Tingarla is visited by a TV crew who is there to document a penguin hatchling’s growth. Fuuka wants to turn down her opportunity to be on TV again.

Aquarium Tingarla is hard at work preparing to carry out the aquarium wedding project that Kukuru spearheaded.
