Soon.

Tak: Why don’t we make some ZERO’S T-shirts soon; fifth anniversary [shirts].
Kara: Sss… well, the thing is, Tak-chan, I started working on them in secret some time before; the design is pretty much finished and now there’s only the fine tuning left.
Tak: Finish it up quickly, please; before N.Y in June ～
Kara: Oh, yeah. Let’s go dressed to match!
