All these other girls could learn a thing or two from Hinata: where everybody else is obsessing over the possible futures and fantasy scenarios with Sou to the point that it completely overtakes their ability to interact with him naturally, Hinata's just going with the flow, living in the moment, and is just happy to have made a new friend.
But on the other hand Kanaria's quivering in her seat apparently really enjoying the bizarre praise NTR she's being subjected to, so, uh, maybe both of these girls are living their best lives. Happiness takes many forms, I guess. I'm not here to judge.
