Back to the au were they are bouth forced to live on the surface, and can't turn back. I hope oikawa can handle it moast of the tume without blaming tobio. But then there are days where oikawas mood is really sour and he cant eaven look tobio in the eyes because it makes him feel eaven make homesick. Simply avoiding tobio. And tobio blames himself more and more so bouth start to isolate themself more or are at each others throat as soon somone says or doas the wrong thing. (I like angst btw;;;)
Yeah, the thing is, Oikawa loves being a mermaid. Kageyama doesn’t hold any strong feelings about it whatsoever but it’s very important to his lover. They live in a community and in relatively close quarters with others and Kageyama doesn’t really like that sort of overly-social environment either, he was even prone to disappearing from time to time before he and Oikawa got together. Now sometimes Oikawa indulges him and leaves with him (sign me the fuck up for that cute romantic mermaid vacation lol), sometimes he lets him have his space but for a short while because they’re too lovesick to stay apart ( ͡° ͜ʖ ͡°) >///<
When they are on surface though, Oikawa feels too isolated and estranged and Kageyama feels good about being so himself because it’s more freeing for him and human world is new and foreign, it’s interesting and it feels like Oikawa and him are together, alone. Oikawa doesn’t see it like that because he needs more social interaction and he hates that his lover seems too focused on outside and he already feels alone so he wants to go back soon. He’s frustrated when Kageyama’s magic does not work. Kageyama becomes also frustrated when Oikawa isn’t happy and that sort of mood isn’t helping them go back in the least.
After a while the root of the problem becomes apparent and Kageyama is somewhat surprised himself that he was feeling that strongly about it. Oikawa is actually touched, even though he was feeling so frustrated for weeks, the reason behind it is just so damn cute. He leaves to find a place in the ocean that is more secluded so Kageyama would be happy with it but not too far from their community that Oikawa would feel isolated. When he returns to him to tell why he’s left, it’s Kageyama’s turn to feel touched.
