Captain Saki calls out for Mano-chan to respond

From about 15:18 to 15:40

Captain:
You know, Mano-chan's birthday is in April. We've exchanged contact details, and we occasionally send messages to one another. But I sent her a birthday message in April, and she still hasn't replied (laughs).

I was pretty shocked. I mean, it's already been about four months. But she still hasn't replied, which personally has me wondering when she'll reply. Mano-chan, please respond (laughs).
