"Aww!" Tao rubbed his left arm which got a sudden punch. "What was that for?" He asked to the person who didn't have a guilty expression after threwing a punch. That person was his best friend, Sehun.

"For not waking me up to watch the firework last night." Sehun still in his flat face. He folded his hands in front of his chest and looked at Tao who was now in front of him.

"But, you looked so..." Tao looked for a suitable word to describe, "Peace." He looked at Sehun into his eyes, "And I didn't want to bother."

"Whatever. It makes you owe me two cups of bubble tea." Sehun smiled while imagining his bubble tea.

"Fine." Tao smiled. "I'll buy them for you." He then turned and walked away.

Sehun looked at Tao's back and felt something was so wrong. "Tao?" He called.

Tao continued to walk away. He got further and further. The front door of their dorm was suddenly getting even further as Tao walked on the direction of it.

"Tao!" Sehun called once again. Tao seemed to have no intention of turning. Sehun started to worry. "TAO!!" Sehun almost screamed as Tao reached the front door which was opened.

There was a very bright light coming through the door. Tao walked into that light and fused with that irritating light. Sehun was dazzled by the light. He closed his eyes with his left arm. And when he opened his eyes, he found himself was laying on his bed. All alone and breathless. That was just a dream. No, that was a nightmare.

Sehun got up and sat on the edge of the bed. He looked at the small clock on the small table beside his bed. It was 2 a.m. He then looked at the other direction and saw the calender hanging on the wall. It was a pretty large calender with EXO as the model. He looked at his picture on it with the remaining EXO members, Suho, D.O, Kai, Baekhyun, Chanyeol, Chen, and Xiumin. He took a deep breath. He then focused at the date and saw a day was being marked. It was 8th of April 2016. The 4th anniversary of their debut day. And that was three days ago.
