Waking up as the rebellious heir

After dying in an earthquake, 22 year old Mai wakes up as a 17 year old girl name Macy. And what’s more is she she finds out that she is the heir to a multi-billion dollar company left to her by her grandfather! But there is a condition to the will. Macy must participate in a series of “challenges” set by her grandfather with other family members in order to redeem the business. If another family member were to win more games than her she loses her rights as an “heir”. In her new life Mai is more determined to live the life which she was not able to. Will she win the right to be an “heir” or will it drop into the clutches of another family member?
