So, I can't remember this CN novel but I really want to put it on my reading list. The ML was rich, but he climbed from the bottom meanwhile FL was an actress but she was really hated to the point people called her the queen of black. ML felt like he no longer needed anything and was practically bored with his life. ML said that he never crossed path with FL, as their only crossing was in a banquet where FL was almost forced by some rich foreign men and she hit her head with a wine bottle saying, "Can I leave now?" not caring about her bloodied head, which left quite a deep impression for ML. Once again, I don't remember how, but ML traveled back when he was still in high school. He then found out that FL was actually his classmate, he didn't recognize her because he never really cared about his classmates. ML saved FL who was humiliated by the teacher. Please help me!
