Dearest Yoona,

I wrote this letter because I'm afraid if I try to tell this in person, I'll just bail and you and forget about anything else. I know it's silly but trust me, I'd give everything to have a taste of you again but I won't because it's wrong. I don't want you doing anything that will hurt him anymore. I don't want to drag you into the mess that is my life anymore.

You're probably never going to forgive me for this. The thing is, I'm leaving. I'm sorry I can't come to your wedding to support you. I just can't be there to witness you commit yourself to someone else for the rest of your life. I don't want to have that memory etched in my brain. I want all my memories of you to be happy and beautiful so that when I remember you, I'll have a smile on my face.

I'm sorry it took me so long to say this but I love you. I'm in love with you, Im Yoona. It's been going on since I don't know when.  You don't know how I wish I was the one you are marrying now. You've been the one who's kept me strong throughout the years. It's time for me to be strong for myself; by myself. That's why I'm saying goodbye to you. I don't know when I'm coming back but I hope and pray that someday, I'll look at you and I won't feel any pain anymore. I know it's mean. I feel really bad that I left you like this. You'd probably hate me because I just ran away but I don't know what else to do. I think it's for the best.

I was never
