The Boat Has Crossed the Ten Thousand Mountains, Beware of Fire, Theft, and Girlfriends

After the Proposal, There Was No Tepidness, a Modern Novel About Treating Each Other as If They Were Guests, and Then They Fell in Love More and More.

I want to read a book like "Two Years After Marriage, My Husband's Ex-Wife Comes Back". It's that kind of story where the male and female protagonists are quite ordinary. Ordinary people get married for some reasons, treat each other as if they were guests, but have no love. Then after getting along for a long time, they develop feelings for each other.
