Listen to me, Hamakaze!

It's great that you've gotten B Kai, right!

You got picked for getting a remodel!

Listen to me!

Anyway, that's my chair! Move!

Ushio.

Have some time off and take her to an onsen or something, would you?

I know all about it! Right from the start!

Breasts...

You're wrong! It's B Kai!

Just B! 乙改 can be read as /okkai/ (otsu+kai), while 'breasts' can be /oppai/; dialogue changed to maintain joke.

I heard you! It's B Kai, isn't it!

That's just short for Breasts Kai, isn't it! Hamakaze says /paiotsu kaide-/, which is a feminine slang reversal of /oppai dekkai/ - 'huge breasts'

Okay.
