Goodbye Summer. (SeStal)

~Based primarily on f(Amber+Krystal+Luna) featuring D.O. of EXO-K's song, entitled "Goodbye Summer."~

"The friend label is a label that I got to hate.

The feelings I've hidden still remain as a painful secret memory."

"I wish she knew..." -Oh Sehun

"I wish he knew..." -Jung Soojung "Krystal".

Oh Sehun and Jung Soojung became the best of friends ever since they were caught talking in the halls, which was a big no-no in their school, Jeguk High. Since that day, they became the best of friends. They shared almost every moment they had together. They were almost inseparable; just like the Astro twins.

Both had feelings for each other-- and it obviously wasn't just as friends. Both Soojung and Sehun liked each other, but were to scared to admit it.

What will happen to Soojung and Sehun after graduation? Will one of them actually gather up all of his/her courage to confess?
