I went into this show extremely suspicious from what I’d initially gathered about it: a guy treating a girl like a dog just isn’t something that appeals to me as as source of entertainment. After this episode, this is still the case, but at least the show is quite clear about Shinohara Erika’s unfortunate situation being entirely of her making, and it’s up to her to get out of it, not anyone else. It’s your typical pride-vs-appearance tug-of-war, and so far, pride is losing out.
Sure, getting to school late on the first day is rough, because everyone’s already split up into groups. But building an empty relationship based upon lies to ingratiate oneself with vapid self-involved girls in the back of the classroom just makes things worse. Like Futaba in Ao Haru Ride, she doesn’t really gain anything from pretending to be friends with them, aside from the appearance that she’s not alone when she really is.
Marin and Aki don’t really give a shit about Erika, regardless of whether she’s banging a model. Even when Erika has Sata Kyouya playing along, the only reaction she gets out of them is relative indifference, followed by mild irritation, since the rest of the school thinks he’s such hot stuff. And the cost of this farce is far too high. At this early stage in her high school life, it would be better to come clean, but she’s not going to do that.
So as I said, the titular situation, in which she must serve as Kyouya’s dog, is entirely of her making. She got him involved in her web of lies, and he’s perfectly willing to help keep those lies going for her, as long as she’s willing to completely humiliate herself. But a part of him obviously cares about Erika beyond “killing time”, so it seems he’s making things hard on her because he hopes she’ll eventually stop with the lies. She has the power to stop being a dog. Will she get the picture? Ehh…I’m not sure I care.
