[Tutor] I'm Just an Ordinary Passerby

Ever since Chiba Yusaki found out that she had traveled to the world of tutoring, she decided to be an ordinary passerby and stay away from Vongola who specialized in slapping people in the face. Hot blood is good, but first she has to fight with her life. After more than ten years of peace, the decision she made that she regretted most in her life was to work in a ramen shop called Lelexuan. What I regret even more is that I met an uncle named Chuanping in that store. What she regretted most was that she actually activated Seven's Cubic Slate, and was told by this broken system that in order to maintain the stability of the world, she must find the wrong points in the world and erase them. Chiba Yusaki looked at the Snow Guardian Ring that appeared inexplicably in his hand in silence, and wanted to tell it that he was actually a time traveler more than ten years ago. But suicide is impossible. She died early in her previous life, and she really wants to live a few more years in this life. Until one day, she discovered Antonio Grice, the young killer who was an extra member of Varian's assassination team of the Vongola family. This is a person who does not exist in the original work. The decision is yours! As the saying goes, a dead Taoist friend is not a poor Taoist. As long as she acts resemblingly enough, the blame for this mistake will not fall on her! Until she continued to act, she found that she seemed to have become an indispensable person in the main plot. Etc! She just wants to be an ordinary passerby! *** Some food guidelines 1: Original female protagonist with tutoring background x original male protagonist (Chiba Yusaki x Antonio), but there are few emotional lines, and the main plot line is 2: The settings related to the Snow Guardian and the ring are original 3: There is no other obvious CP description 4: All plots only serve the plot Purpose: Never give up easily when encountering difficulties
