Reborn in 1990

あらすじ

He died a broken man — betrayed, ruined, and alone. But when he wakes up in 1990, one vow drives him: clear his name, crush his enemies, and fulfill the promise he made to the only woman he ever loved. Starting from a tiny factory, he’ll outplay tycoons, beat foreign giants, and rise to the top of high society — building an empire no one can destroy.
