Schoolgirl Miho Fujigasaki has been living with her father for a while since she lost her mother who was an oceanographer several years ago.
My father was the captain of a large cruise ship “Northern Light”, but I went down to catch my mother’s death.

However, Miho noticed that his father wanted to return to the ship’s work at some point.

Miho, who has become able to do housework by himself, backs up the father’s back who has been lost and recovered from a colleague at that time.

Then, the father who was to return to the ship worked for a while as a deputy captain, and finally the formal return to the captain was decided.

It just says it will be a memorial cruise for the “Northern Light” 200th voyage.

Such a thing, Miho is brought up with a certain talk from close friend Jun Moribe.
In the commemorative cruise, I was invited to join a part-time job because I am recruiting a part-time job.

It’s just during summer vacation, so it’s also time to get wet, so I’ll be invited to Miho.
Then, with Jun, it is decided to participate in the father’s memorial cruise return cruise.

The summer vacation is over, and after a few days of training, the voyage begins.

While struggling to get used to a part-time job, I get close to the idols of the idols doing events on this cruise, the students and the violin player Saki Otowa, the casino dealers, Nadia Mizuna , etc. and have a good time spend.

This summer vacation will be a lifetime of memories ….
Although it was Miho who was convinced so, I did not think that a nightmare was waiting ahead of it.
