Dear X (2025)

"X" Marks Her Next Victim

Original title: 친애하는 X

Behind a beautiful face hides a cruel nature—Baek Ah-jin, who sees through and manipulates others' hearts. After stepping on the sacrifices of many to reach the top, everything begins to change the moment she arrives there. A woman wearing a mask to escape hell and climb to the highest place. And the story of the Xs being brutally crushed by her.
