help a friend out(づ￣ ³￣)づ

i could've sworn it was called like "finding ray".
i'm looking for a yaoi manhwa where it's set in modern day but there are people with supernatural powers. some work for the police, some work for the mob, & some in organizations. the protagonist is a twin who recently lost his brother. i think one of their names is ray. they were separated when adopted by 2 different households, but meet up time to time until his brother disappeared. the protagonist was adopted by a loving family while his brother adopted by an abusive one. some blonde dude comes into contact with him bc be inherited his brother's powers or somethn & he's in danger. he learns this whole different universe exists & is then training to control his powers. they eventually get into a relationship but the blonde's very "protective" of him & locks him up. he tries to escape but the blonde's power is it to block a magic user's power or somethn. he eventually finds his brother who was taken by some mob boss with a snake tattoo. i would be so grateful whoever lets me know(づ￣ ³￣)づ
