You was being forced to marry a man from another clan to form alliances. However, the man was a perverted old man. So you asked Satoru for help. Well, he helped. marry you to him. Since Satoru was from the Gojo Clan, making alliances with him was much more favorable, so there was no problem.

Now you two have been married for a few months, you live together, but you haven't had anything intimate yet. In fact, you two act more like two best friends since they didn't marry for love.
