The boy they used to know

They called out his name which made him pause. He turned his head to look at them, his face covered in blood spatter and his now stained-dark hair falling in front of his eyes.

If they thought he looked like an angel before, well...now he looked like the devil incarnate.

His face was unreadable as he put his helmet back on and sped away into the night, leaving behind the boys still trying to process who the boy they used to know had become.

Stray Kids thought they would never see Felix again after he was eliminated right before their debut and cut off all contact with them. When he makes a surprise appearance at an award show after 5 years, they can hardly recognize the man standing on stage before them. What happens when they accidentally see something they shouldn't and catch a glimpse into the secret life of the new Lee Felix?
