It's been a while since the last time we saw the two of them together, and now that they're back in Japan, we catch up with Keita. She's on a trip with igarashi, and she asks him why he doesn't call her by her first name, instead of his last name. Keita says that she'll feel "distanced" if she calls him "by his first name" , but she's not sure that's the right way to do it, so she decides to call him by "his blush first name."
