Actually, it was a forced marriage. If you look very closely, it says that they liked each other but were not in love. Even though that doesn't make it better, its good to know that she didn't have to deal with the man she loved cheating on her. Just the guy she was forced to marry.
I like the story but only one think I am not satisfied is about shina-san's wife. She had to live with a man who does not love her but is in love with his brother -in-law. The father was already cheating on his fiancee at the time and i can't get it out of my head because I hate cheaters and that was exactly what the father did and shina-san did not feel any guilt in sleepin with his sister's fiance but I am glad that they got together at last and have their happy ending.
