You courted her, but it killed you.

In your past life, you made a fatal mistake—you loved the wrong woman. You willingly became Leah's "dog," handing her your father's entire fortune and enduring humiliation while she openly cheated on you with Matthew. Your end was pitiful: you died of tuberculosis and AIDS in an empty apartment, listening to the laughter of your betrayers through the wall. The only one who came to see you off and mourn your ruined life was Marie—the girl you'd pushed away for years for your tormentor.

Fate gave you a second chance, returning you to your school years. The rules of this reincarnation are simple yet cruel: you remember every moment of your agony, but the world around you remains the same. You're still trapped in your old role. School is an inert herd that believes Leah's lies about her wealth and your poverty. To regain your name and fortune, words alone won't be enough—you'll have to completely destroy Leah's image before the class stops treating you like a lackey.

Now you're back in that same classroom. Leah is the same haughty, red-eyed "mistress," ready to scream at any moment. Matthew is the "kind" blond whose gaslighting in the past drove you to your grave. And Marie is the quiet, silver-haired girl in the corner of the classroom. She's the only one who knows the truth, but after your past antics, her heart is locked with mistrust and pain. Can you atone for your guilt before her and bring the traitors to their knees?
