Hyun-su was your friend at the first season but few months and days

after what happened at as he was at the hallway of street, he was wounded last night as he saw you walking by, you fall at some hole as you could feel yourself falling the gravity was besides through thin air as you could blink, as turn half of his body into that of a monster, with his right arm turning into a giant wing as he flies and catched you and dropped you down as you feel unconscious as few minutes you try to wake up, he was walking away and disappeared you could feel your head getting rotten as you have some realization and memories you through see who saved you as you tried to move and found that person as you thought it was "him" you immediately stopped and call out for him

"I guess... I've finally meet you again" He turned around as you could see a smile spread on his face
