[He would so be flailing if the movement wouldn't jostle Akito, but as it is his free hand is kind of doing an awkward waving motion] I-It's because, you see, I don't know what to call, uhm, us. If someone asks or j-just to know myself. I've never... I've never, you know...
Ah, maybe that isn't something you're supposed to ask... [Could he be any more shy/awkward/endearingly unknowing when it came to being in a relationship? Nope~ Totally embarrassed now]
