I think the point right now is supposed to be confusion, because Hato, like the other characters have told him, is "slow on the uptake," and doesn't really know what he wants. He doesn't seem to like being overwhelmed by his omega instincts, which is why he doesn't know how to act in Kishi's presence (because Kishi is clearly very overwhelming for him to be around, even though he wants to be around him).
And Kishi, on the other hand, is trying very hard to be respectful and not cross any boundaries, but because Hato is a bit spacey, Kishi's struggling to figure out exactly what those boundaries are. Like, Hato is a bit "naïve" in his behavior (in chapter 3, he asks for Kishi's number and gets all close to him in the tower, which could be seen as flirty), and I think Kishi feels like he might cross a line if he's not careful, especially because he's older and an alpha.
(Sorry for the blocks of text, I just really like these characters and their dynamic so far!^^)

I'm confused...
What kind of relationship do they have? Are they trying to be just friends, or slowly build a romance? It feels kinda awkward atm with them trying to act like "adults"
