Comment by Liliana Vave on Galactic Navy Officer

@Liliana Vave Koushaku Reijou Ni Tensei Shiteshimatta Node, Mental Otome Na Ore Wa, Zenryoku De Onnanoko Wo Tanoshimimasu is also cute. It starts as an arranged marriage (for the future, they're both kids), but they grow to like and respect each other. And they find out they share an interesting (good interesting) secret. When that secret's revealed, their relationship takes on a new level of adorable.

It's complete, but the manga had to speed run the ending compared to the novel, apparently because the author got a cancellation notice. But the author manages to speed run it well, without any plotholes or deus ex machina.
