After Reading the Book, I Accidentally Found the Heroine of the Original Text

Double heroines [The sinister senior sister x the innocent junior sister] [Through the book] [be] Just because I stayed up late reading a novel, I was so angry at the behavior of the male protagonist in the original novel that I inexplicably traveled through time and became a passerby with the same name. The system told him that he needed to protect the heroine to complete the task of defeating the demons, and he could not let the heroine die during the process. Jiang Jin could only agree with tears. But I watched the male protagonist try to use his dirty hands again and again, but he was easily resolved every time. And because of an inexplicable mission given by the so-called Lord God, she can only protect the female protagonist from being harmed by the male protagonist while performing the mission. But why is the heroine looking at me more and more strangely, and I seem to be turning her into a yandere? The heroine in the original text picked up Jiang Jin's hand and put it on her face, with a dark look in her eyes, "Don't leave me, okay?" "I'm better than him, but he can't be better than me." "Isn't it bad to like me? Why should you look at others." Jiang Jin screamed crazily in his heart: No, where did the original senior sister Wen Wen go? ? ? I don't want a sickly heroine!!
