I Blocked My Online Crush After Finding Out He Was 5T5 [Crossover]

My name is Fujiwara Chihai, and I'm a "normal" high school girl attending Rikkaidai High School. My biggest dream in life is to live an ordinary life and marry an ordinary guy. But who could have guessed that everything would end up going completely against what I had imagined? When I discovered that my online boyfriend was actually the strongest sorcerer in the jujutsu world, I immediately deleted and blocked him, afraid my future might accidentally stray from the path I wanted. But who could have guessed that curse spirits would keep appearing one after another, catching me completely off guard? In the end, I had no choice but to go study under my former online boyfriend and immerse myself in the classics (not really). Heh, so you're curse spirits? Special grade, huh? You think you can bully me just because I'm not much good at fighting, having come from Yokohama? Just wait until I've finished learning. I'll beat you all to a pulp. * Before 5t5's identity is revealed: Chihai: Huh, so you're the strongest? That's amazing! Could you teach me too? After 5t5's identity is revealed: Chihai: Pfft, get lost! [Deletes and blocks him] Gojo Satoru: ??? * Reader's guide: ① The pairing is Gojo Satoru, and he's also her online boyfriend (yes, this is a true "I can't help falling for him" story). ② The timeline has been changed, there are original character details, and all sorts of death flags will be kicked away. The romance will develop gradually along with the plot, and there's plenty of sweetness. I really couldn't keep reading the Jujutsu Kaisen manga, so I'll only write up to Shibuya. After that, the story will be changed beyond recognition. ③ This is a long novel, estimated at 300,000 words (don't believe me, I've never gotten my estimates right). ④ The anime series expected to appear are Jujutsu Kaisen, Bungo Stray Dogs, Natsume's Book of Friends, The Prince of Tennis, Kuroko's Basketball, Detective Conan, and Katekyo Hitman Reborn! ⑤ This blurb was written on May 17, 2021. The inspiration came on April 19, 2021. I have screenshots of the detailed outline and character profiles. ⑥ Your author is dedicated to writing fanfiction. Won't you come take a look? (Behaves nicely) If you're okay with all of the above, then let's go! Premise: Written for Gojo Satoru! Yay!
