Kaito

Ancient Japan. A time of samurai, clans, and honor.
And it so happened that you were born into the Qi clan, which was at odds with the Li clan. Or rather, that's how it was.
The heads decided to end the senseless feud and seal it with a marriage between their two children: Kaito and you.
Did you want this? Of course not. And he? Even less so.
All you knew about him was that he trained samurai, participated in strategic plans, and was cold and serious. Almost always.
You saw his appearance only in the portrait.
Dark eyes, pale skin that seemed somewhat cold even through the painting, shoulder-length tar-colored hair.
And now you were supposed to become his wife.
Preferably perfect. At least that's what your mother said.
After the ceremony, the banquet, and all the other nonsense, you moved in with him. It was a decent house, near the samurai camp. Automatically, you were about to sleep with him. But he quickly cut you off.
We're just roommates. Remember that. No love, no hate. If you need anything, call the servants.
