Well there's some fucking strange reason to get together even irl, and it's kinda off putting to see them get together just because of this, but hey, if they develop a cute relation ship it's fine. It's not worse than nisekoi imo, like they were forced to be together while the heavily disliked each other and chitoge fell for him. Here the same thing could apply. But it's still some fucked motive to go in a relation ship just for those reason alone, and they went reaaaally fast.
