Become the Protagonist's Best Friend

It's a story about two teenagers who were initially suspicious of each other, but later silently gave their hearts to each other, but they didn't know anything about it. — Ding Lixue was bound by the system and passed through the book. I don't know anything about the book or the plot, but as long as I complete the mission, I can go home - become the protagonist's best friend, promote the development of the plot, help him rise to the top, and finally escape, which becomes an opportunity for the protagonist to explode. According to the system, the protagonist is righteous, unyielding, and gentle, so the task should be very easy to complete. That's what he said... Ding Lixue raised her eyes and glanced at the protagonist, with a smile on her lips, but her eyes were full of anger. She raised a blackbird that was only related to murder cases and carved wooden objects all day long. He played with the stone in his palm. This stone was picked up from the murder scene, but it had a resonance with the person in front of him. What about being pure and kind, righteous, unyielding, and gentle as jade? The difficulty of the task of "becoming the protagonist's best friend" increases rapidly. Oh, there is also an additional task of "bringing the protagonist back to the right path". After that, they were suspicious of each other, but at the same time they tacitly agreed not to expose each other's disguise. On the surface, they are good partners who will give each other's back. In fact, only they themselves know that it is just a bundle of interests and they break up at once. Ding Lixue didn't think she was really that capable. She could persuade a paranoid and vicious person to become the person the system said she was, and she couldn't really turn around a relationship that was initially purposeful and tentative. But according to the development of the plot, it was only at the plot point of the death escape that he saw the settlement point and the emotional value of the protagonist towards him. Full value. — Min Ciyu had been planning revenge since she was a child. Several years had passed and everything was going smoothly. However, at the end of winter, she was slightly disrupted by a "little distinguished guest" who appeared from nowhere. Separated by a wall, he was deliberately surrounded by others. He knew that the other party was outside the wall, but he only heard the sound of trampling fallen branches. As light as falling snow. Min Ciyu thought, indeed, everyone approaches for benefit. He knew it, but he still walked hundreds of miles with him holding the sword. After walking together for several years, Ding Lixue felt cold all over, but the warmth of the embrace had already dispersed the remaining winter, and the light fragrance of magnolia enveloped Min Ciyu. He doubts, believes, and is ignorant. The separation without a word of farewell woke him up completely. It took the young man many years to understand the ignorant feelings among young people at that time.
