Magari Kado no Kanojo(2005)

Magari Kado no Kanojo is a Japanese drama series about ambition and rivalry in the corporate world. Oshima Chiharu, a 33-year-old sales and planning director at a luxury hotel, has spent her career climbing to the top. Her carefully ordered life is disrupted when Natsumi, a seemingly naive 25-year-old colleague, reveals herself to be a cunning strategist with her own ruthless ambitions. Fluent in multiple languages and willing to exploit every advantage—including her charm—Natsumi sets her sights on Chiharu's position. Raised in poverty without a father, Natsumi is determined to claw her way up the corporate ladder, even if it means destroying the woman above her. The series explores how far two women will go to succeed in a competitive workplace where only one can win.
