I'm so sorry for the way things turned out, and I know I hurt you. I never meant to cause you pain. I just want you to know how much you mean to me.
You are the most important person in my life, and I can't imagine a day without you. My heart is full of love for you, Iffu. Please forgive me.
I promise to always cherish and respect you. Please give me the chance to make things right. I will do anything to make it up to you.
With all my love,
Your [Your Name]
