Fantasy: the Childhood Sweetheart Who Became the Heroine of Her Own Novel

Fang Lang is a time traveler. He traveled through time and became a supporting character in his own novel. He's the kind of person who has no sense of existence and is dispensable. But there is something special about this supporting role. He is the heroine's childhood sweetheart. He is also the original fiancé of the heroine. What to do, what to do. He looked at the protagonist walking towards him with a knife. There was really no other way, so Fang Lang had to silently take out his keyboard and modify the plot. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
