Comment by Kesmeray on Under the Green Light - Chapter 67

 

Blood Bank (dark romance, control, and supernatural)

 

Yours to Claim (not exactly mafia-themed, but it involves control and possessive love)

 

Thirst (crime, dark romance, obsession)

 

Sadistic Beauty (mafia, crime, gang life)

 

Path to You (mafia-like themes, crime, etc.)

 

There’s also another manhwa: Walk on Water, by the same author as Under the Green Light. I haven’t read it yet, but I’ve heard it involves dark themes, emotional conflict, and power imbalance.

 

(I apologize if these aren’t what you’re looking for. They involve themes like darkness, crime, obsession, mafia, and similar genres.) Ik there's more but I cannot think of any more 😭
