Who Wants to Be Best Friends with That Jerk Okkotsu?

I, Shinomiya Rii. Undeniably the strongest first-year at Jujutsu High. Then Yuta Okkotsu's cursed spirit punched me into a serious injury, leaving me lying in the dirt like a dog with no dignity, and my title as the strongest fell apart along with me. Yuta Okkotsu and I are sworn enemies! And that's not all. The day before I was supposed to go on a mission with Okkotsu, I left standing up and came back lying down... The only good news was that I seemed to have returned to Yuta Okkotsu's past. A special grade getting bullied into this state? I showed plenty of restraint by not laughing out loud on the spot. After all, he did something so awful to me. It wouldn't be too much to get a little revenge, right? What about the consequences? Come on~ I'm the strongest at Jujutsu High. If I can't beat special-grade Rika, surely I can beat the pathetic Okkotsu he is now? I'll make him realize that without Rika, he's nothing! Besides, I'm his “good friend.” How can hurting him, when I have no choice but to help him understand his own strength, count as bullying? Still, he's way too easy to fool. Show him a little kindness and he clings to me. There's no sense of accomplishment at all. Just as I was starting to get tired of this boring game, I returned to the present. Only the other person involved seems to have regained those memories too. Then won't all my attempts to act kindly toward him for revenge look like I'm trying to please him? He'll definitely think I'm a joke, absolutely! I hate it, I hate it, I hate it! I hate Yuta Okkotsu most of all! * A comeback story * Yuta/Rika is broken up, Yuta/Rika is broken up, Yuta/Rika is broken up * Third-person narration, paired with Yuta. Some original elements. * It really is bullying! If you don't like this kind of thing, feel free to leave. * My version of Yuta has a gloomy, obsessive streak. OOC warning. * The heroine's title as the strongest is a result of people going easy on her. She's called the strongest, but in reality everyone dotes on her. Theme: Treat others sincerely and reject hypocrisy
