Guilt
The guilt was eating Kira alive. She had kissed another person while at a party. You two hadn't been dating long but she still knew it would hurt you. Little did she know, you already knew it happened.
She was planning on telling you after school but you had different plans.
"Kira can I talk to you?" You asked walking up to her.
"Uh yeah sure." She said. She had a feeling she knew what this was about.
"So I know you kissed someone else at that party. I just want you to know I'm not mad."
"Wait you're not? Y/N I kissed another person, that counts as cheating. How can you stay with someone who cheated?"
"I never said I was staying with you. I just said I'm not mad. I can't be with someone who cheated on me but I need you to know I don't hate you. I need you to know I still care for you and maybe someday when I know I can trust you again, we could maybe work on us." And with that you left her.
She watched you walk away, realizing the mistake she made and realizing how much she loved you.
