From MangaHelpers:
Kida Akane had her life planned out. Her plan was to graduate college, work at an elite company and then have a marriage that everyone was envious of. But all that blew up when her parents passed away with an enormous loan and left her picking up the pieces. She was just about to take her own life when she miraculously meets Tojo Reika who looks almost identical to her. Unlike Akane, Reika lives gorgeously with a loving but over protective husband. But the grass is always greener on the other side and Reika believes that all the money in the world is useless without personal freedom. Akane and Reika agree to swap lives and enjoy the life they have only dreamed of.
