I came to this world five year ago when whole world was fighting against dungeon monsters.

After confirming that he came to solo leveling world.

He panicking about his little life and he also found out of his family/background he is sung jin woo's big brother. He is two year older than his brother jin woo.

He also has younger sister Sung jin ah.

After five year, father gone missing in portal, mother was in coma when dad was missing.

Jin woo stop studying after high school

And became an hunter.

And I sung jin sin became an 'c - rank hunter'. In five years I have been going to dungeons non stop and earning money to pay mothers medical bill and jin ah's school fee and living expensive.
