I love my family too much, that’s why I can’t get divorced

One day, I found myself inside the world of a novel. But of all people, the one I possessed was a super-ordinary supporting character—with light brown hair and brown eyes. I had planned to live quietly as a plain side character and keep a low profile… So how did I end up marrying the heroine’s father?! My plan was simple: live a moderate married life, do my absolute best to make the still-young heroine happy, and then get a clean, tidy divorce. But the daughter is too adorable, and my husband is way too handsome… What on earth is going to happen to my divorce plan?!
