[Hiyori is a receptive audience to all of Elan's tales. Not just because it's his "cover," but because he really is happy to hear more about Elan's adventures. (And perhaps it's also a little cute to see him talking so animatedly.) They don't encounter anyone from his unit in the hall, though, so in the end, there was nothing to worry about.

Which Elan points out once they get to his room. Hiyori hovers at his side in the hall, waiting for him to open the door.]

Who was worried? I knew Elan-kun would protect my "good boy" image.

[There's no one watching and no one listening. But just in case, he lowers his voice so only his date for the night can hear.]

At least until we got to your room, anyway. I don't plan to keep it up past that point.
