The gangster's in love with Han-Gyul's older brother, but he was destined to be with Han-Gyul. After Eun-han made the wish with that spirit, the red string between Han-gyul and the gangster(can't remember his name) was severed and Han-gyuls string is tied to Eun-han's string now.
Is he in love with the older brother? Or was he meant for the younger brother ?
