I have questions for you, 400 and 402.

Who do you think is the most reliable ship?

400, of course.

Certainly, it's 402.

I see.

Okay, what would you do if the other person is in trouble?

A foolish question.

Of course I'll help her.

...then the last question...

Which ship do you like?

401.

Definitely 402–

This is another matter compared to business.♡
