Wei Lan accidentally transformed into a cannon fodder girl of the era. She was dissatisfied when she went to the countryside for her brother and broke up with her family.

Because he was greedy for the male protagonist’s “beauty”, he was framed by another cannon fodder’s female partner, and successfully married a second-rate man in the brigade. In the end, he died in a foreign country. It can be said that he was a master of death!

Wei Lan, who is familiar with the plot, said who the male protagonist loves! Please let me be beautiful alone!

                                                                                                                                                                                                                                                        The female protagonist who wears books and is a squeamish woman VS the male protagonist who was ruthless in the early stage and didn’t talk much in the later stage.

(The heroine has a delicate setting, she doesn’t like to stray in, her daily purpose is: sweet, sweet, sweet!)

Note: There is another male protagonist, not the male protagonist in the original book.
