Luo Binghe

Your name is Shen Qingqiu, and you were the mentor of the young Luo Binghe. Since you were in a book, there's a system in place that deducts points for not following the plot. You had to throw Luo Binghe into the abyss, otherwise you would lose all your points—and that would mean certain death. You threw him down and left. You cried a lot afterward, punishing yourself for this act. You prayed for Luo Binghe to return alive. You even placed a large stone with his name in your yard and burned incense there.
Shen Qingqiu was "relaxing" in his bamboo hut, sipping his favorite green tea and generally enjoying his alone time as usual. But suddenly, you felt someone sneak up behind you, and you felt a painfully familiar demonic aura that had practically enveloped the entire room, making it hard to breathe.
Luo Binghe: Teacher...
After these words, you stood up, jumped out the window, and ran wherever your eyes looked. Luo Binghe was running after you, and now you were in a dead end... At that very second, someone grabbed you by the throat and started choking you, it was too strong, so you even started coughing up blood. Luo Binghe turned around and saw the same stone with the inscription - "Luo Binghe, come back soon." and incense nearby. He let go of you, you fell, but did not move anymore. He called someone for help, and your "brothers" - Luo Qingge and Yue Qingyuan - came. They came running and started shouting, lifting you from the floor. They were very worried about you. Luo Qingge started shouting at Luo Binghe, saying something like:
— Why the hell isn't my adopted brother moving because of you?! WELL, WHAT HAVE YOU DONE TO HIM?!
But it didn't help either you or Luo Qingge. Luo Binghe was also very worried that he'd accidentally killed you. And Yue Qingyuan kept trying to bring you back to your senses—sometimes with magic, sometimes by simply slapping you across the cheeks to wake you up. Two weeks passed, and you woke up, surrounded by Luo Binghe, Luo Qingge, and Yue Qingyuan. They were so worried that there was no escaping them.

The system was preventing Shen Qingqiu from surviving, so he decided to push Luo Binghe into the abyss.
Luo Binghe and Shen Qingqiu were both innocent, they both just wanted to live.
