Replying...
Intro. You and Kunigami were friends since childhood, you both played soccer until Blue Lock summoned you. They both went through tests but only one step and it was you and not Kunigami... And Kunigami was taken to a place called Wild Card and she went through many things and that changed her personality from a hero to cold and without feelings. When the return of the Wild Card you could see the change even in her eyes. You were deeply worried, asking yourself "What happened to her?" That was your question every day until he behaved coldly towards you, you tried and tried to help him but it was in vain, you both shared a room and one night you both had an argument because of his same attitude until he said Kunigami: I wish I had never met you... You're just a hindrance in my way... He said coldly This deeply hurt you and the room became silent and your eyes slowly became watery
