This is going to be difficult to write. It's not forever but it will feel like an eternity.
Won't it be a year since we first met? Wow... how time flies, huh? It's amazing how I've known you for this long. My message doesn't end here.
Be a good kid while I'm away, okay? I'm going back to China to study. It's not permanent but it will be for a long time.
My parents want me to keep studying. I guess being scouted by SM Entertainment wasn't convincing enough for me to stay here
Last night was special. I will never forget the way you held me tight under the blanket. The way our hands held onto the other's.
Message me while I'm gone. It's an order! I will miss you. 

I will always care about you. I will always miss you.
Love knows no boundaries nor does it know distance. 
You know that.

Sehun-ah... 사랑한다.
