my name is oh sehun. i am a sophomore at shinhwa university.

in the spring that i was nineteen, i recieved a rather detailed letter from myself, ten years into the future.

at first i believed it was a prank but sure enough, all the events described inside began to unveil in that exact manner. from waking up late to the arrival of a new transfer student named kim jongin, this letter is advice from the older me to erase any regrets i will hold until the day i die. 

most importantly, in this letter, the twenty six year old me informs me that the biggest regret i will ever have is that kim jongin is no longer with us in the future.

i have been asked to watch him very closely.
