Yung-hoo was just doing his Duty like always around the streets of korea,flying around,stopping crimes etc...

Until he got badly injured when he was saving a 9 year old kid from an extremely dangerous fire that was set in a tight apartment.

After the successful rescue,he flew up trying to locate his house but he lost his balance and fell on a random balcony,he was tired and crushed,his arms were all burned,he had cuts all over his body,he was a mess.

He dozed off for some seconds there and when he woke up,he found himself laying on a comfortable bed in a random bedroom,He got up on his elbows and looked around the room still trying to process what happened but he was all tired,he couldn't even move an inch so he just snuggled back into the sheets while his wounds were starting to heal,Looks like that "supernatural" body of his finally started responding
