Oh Sehun raised a brow and crossed his arms over his chest. It was almost midnight and Sehun was surprised to see Luhan still up doing the same thing he was doing in their dorm living room after they ate the dinner that Kyungsoo and Chanyeol prepared for the twelve of them. "Hyung, you're still at it even at this time of the night?"

"Yeah." EXO's second eldest member, Luhan, replied without looking at Sehun. The latter shrugged his shoulders, walked inside the kitchen, took a bottled water from the fridge and went back to his room. Luhan's eyes never left the Rubik's Cube in his hands as he was halfway done solving his 25th cube. Even when another member sat beside him, Luhan's concentration never wavered.

"Luhan..." *munch, munch*

No response.

"Sigh. Lu ge~~"

Luhan momentarily looked up from the object in his hands and turned to his right. "What is it, Xiumin?"

The older boy mischievously grinned at Luhan and shrugged while munching on his Mocha bread. "Nothing. I just wanted to disturb you."

"Aish." Luhan made a face and went back to solving his cube. Xiumin leaned closer and eyed the colorful cube that was almost solved. "You have solved 24 of those and they are all stocked up in your room. Why are you solving another one?"

"The Rubik's Cube's Anniversary is on May 19."

"That doesn't really answer my question, Lu."

"I bought forty rubik's cubes."

The elder boy's eyes widened in surprise and a piece of Mocha bread almost went out from his mouth. "Ehh?! What for?"

Luhan grinned and showed Xiumin his 25th solved cube, admiring the uniform colors from all sides. "I'm solving 40 Rubik's Cubes for its 40th Anniversary."
