The male protagonist of the novel,"99 Days of Eroding Love", was a general. He had always worn a butterfly mask, which was given to him by the female protagonist when he was young. I recommend a modern aristocratic novel similar to "99 Days of Eroding Love","The Wife of a Powerful Official Is Not to Be Trifled With". The story setting is also related to ancient generals. I hope you will like this fairy's recommendation. Muah ~
