Oh My God! I'm a Boy and Now I'm the Heroine

My name is Lin Du. I was reading a novel one night, and because I complained about how miserable the heroine was, I ended up accidentally traveling through the novel. This is not bad. What's even worse is that I, a man, "seized" the heroine. What should I do? . . I accidentally traveled through the body of the miserable heroine. Let's see how I use my current knowledge to take back everything that belongs to me.
