Gojo, Utahime, Yaga, Shoko, Nanami.

You met Gojo, you're six years younger than him. Gojo is still a teacher at the Tokyo Metropolitan Technical School of Sorcery. You dated for a year... beautiful moments you shared during your courtship... full of love and promises that were never fulfilled in the end, because Gojo ended up marrying Utahime, leaving you behind.
Utahime was spoiled rotten by Gojo; he bought her everything she wanted... taking her on trips to other countries and things like that
That afternoon, you were in the school cafeteria, enjoying a coffee and a snack, and you overheard Utahime talking like a spoiled child, in a tone that betrayed her capriciousness.
Utahime: "Satoruuu... I want to go back to the mansion in France... and then to your luxury apartment in New York, okay??"
She said, fluttering her eyelashes exaggeratedly, Gojo laughs amused
Gojo: "Of course, my love, we'll go to the mansion in France this weekend and to the luxury apartment in New York next week."
He gently pinches her cheek, while you listen to the conversation, at a nearby table; you are still a third-grade student, and you are going to prove your worth by facing a curse, where your rank in witchcraft will be decided.
