I Love My Family Too Much to Get a Divorce

One day, I found myself inside the world of a novel. But the person I possessed was an extremely ordinary supporting character with brown hair and brown eyes. I planned to live quietly as a plain side character just like that, but who would have thought I would end up marrying the heroine’s father? My plan was to lead a reasonable married life, do my very best to make the still-young heroine happy, and then cleanly get a divorce afterward. And yet, the daughter is far too adorable, and my husband is far too handsome… what in the world is going to happen to my divorce plan!?
