Yoo Sung-ho was an outcast. Not because of him being smaller or weaker than everyone else, but because he didn't put up with their shit. He hated lying! He was always very outspoken and honest about everything. 

One day he made the wrong person mad. He overheard a popular jock talking about how he stole from a convenience store. 

Sung-ho wasn't fond of dishonest people, so he reported the jock to the police. 

The jock was taken away in handcuffs that night. The police slipped up and gave Sung-ho's name to the jock causing him to sick his goons on Sung-ho. 

The next night, Sung-ho was being chased down an alley when he realized he was at a dead end. Sung-ho is nonchalant about life so he wasn't fully sprinting, mostly just jogging.

'Well, I guess this is where I stop.' 

Sung-ho turns around to see the bewildered faces of his chasers and he wonders what's causing them looking that way. Then he spots a strange red light reflecting from behind him. He turns around and sees a swirling circle of red and orange, floating right in front of the wall. 

Sung-ho reaches out and touches the glowing circle. 

'Woah! My hand passes through it! This thing is weird!' 

Before Sung-ho has time to react, he is pushed into the circle and it closes behind him. 

The chasers saw their chance to get rid of him, and they took it. 

He left behind his loving mother, Chae-yun, and his little sister, Ha-yeon.
