My Fiancée Is a Spoiled Brother’s Keeper

I read this book today and was seriously disgusted. It's not a problem for my fiancée to kiss me with another man. Instead, the attitude of the prospective mother-in-law is the key point. It is forgivable for the fiancée to let another man sleep with her, but the attitude of the prospective mother-in-law is unforgivable. There are many wonderful things in this weird world, and I saw another one today.

If you can't write it, don't write it. Where's the Lamborghini you promised at the beginning? Secondly, don't make the protagonist too soft-hearted, okay?
