I Lost My Memory After Vowing to Be Together Forever with 5T5

[Upcoming: What Should I Do When My Best Friend Suddenly Confesses? Please add it to your favorites!] Blurb: As a child, Nura Riku once wandered into the Gojo estate and met a little boy. His hair was as white as snow, and his clear blue eyes were as bright as the sky. The girl sitting in a cherry tree fell in love at first sight and waved at him without hesitation. "Hey, I like you! Will you marry me when we grow up?" After spending a year winning the boy's affection, Nura Riku was tricked into forgetting all about it. Then, in the spring when she was about to take the entrance exam for the University of Tokyo, a blind man wearing sunglasses took her hand. After her memories returned, Nura Riku couldn't understand: How had the aloof and noble child of the gods she'd known become an annoying pest who meowed all day long? The strongest sorcerer has told everyone at Jujutsu High: "I've got a gorgeous girlfriend who loves me to pieces!" "She proposed to me ages ago, you know~" The people at Jujutsu High have never seen this fiancée, and they all think he's lost his mind. Even his best friend doesn't believe him and kindly suggests he play fewer dating sims. To everyone's astonishment, one day they see a huge cat of a man clinging to a petite girl and wailing dramatically: "Riku, open your eyes and take a good look! I'm your handsome, number-one-in-the-world fiancé, lost to you for years~" Then she knocks him into the wall with a wooden sword. P.S. 1. The heroine is strong and beautiful. 2. The story focuses on Jujutsu Kaisen. Please don't overanalyze the details. 3. I'll add more if I think of anything (scratches head).
