Li Jin was tricked into a blind date by her eccentric aunt. The man was supposedly an "honest, introverted" engineer.
She pushed open the private-room door and came face-to-face with a man whose presence was overwhelming and whose gaze could freeze people to death: Li Zhanye, the living King of Hell whom no one in the capital dared provoke.
Li Jin: "...Sorry, wrong room." (Inner thoughts: This engineer is way too handsome. He doesn't look like a good person, though.)
Li Zhanye: "A new trick to play hard to get?" (Inner thoughts: At least this woman acts better than those socialites.)
She meant to leave at once, but the King of Hell grabbed her and dragged her into a contract marriage, making her his shield.
Fine. As long as there's money in it, I can enjoy some peace and quiet.
Until one day, an assassin broke into the villa.
Li Zhanye had just grabbed a weapon when his "fragile, helpless" little wife slammed the intruder against the wall with an elbow, then dislocated his jaw with a swift reverse move. She moved like a ghost.
Li Jin dusted off her hands. "Tsk. You woke me up."
Li Zhanye: "...???"
Later, rumors swept through the capital:
Lord Li's contract wife, the one no one thought worthy of him, was actually the top hacker known throughout the underworld as "K"!
She was also the bloodthirsty "Dark..." who had never lost a battle in the underground fighting ring.
I think the emotional plot is all done slowly, and neither the female protagonist nor the male protagonist is a love brain [I understand]
It's very beautiful, and the story has interesting twists and turns.
