Regret.

Was all on Mark's mind while watching the man who he thought would have been his if he realised that he loved him sooner.

Pain.

Was everything he felt while watching him smile and hug someone that is not him.

And Guilt.

Because if only he treated him better the moment he had the chance, he could've been his. That there was no one to blame because in the first place, he was the one who pushed him away.

To watch them look so happy and the way they talk about their future in front of their friends, in front of him. Was painful.

"I'm happy for you, really" he assured the smiling Donghyuck while holding Renjun's hand.

"Thank you, I'll go greet the others" he said while pulling the other man's hand on the other side of the room.

"I heard the new group will be coming today" Doyoung suddenly said as he stood near the counter next to Mark.

"I heard that too." Mark replied downing the liquor he acquired when he entered the room.

He was at Donghyuck's new home, apparently the couple decided to move out together.

"Don't get too drunk, you might not control yourself" the older said while taking the empty shot from the younger's hands.

Before he could protest, the older muttered a "here they are" before disappearing to he don't know where.

He shook his head and went near the fridge to get a new drink.

"Having a tough night?" a voice said from behind.

And when he turned to look; a tall, handsome tanned man was there, and he smiled,

"I'm Xuxi."
