7 Days to Kill the Past

Ten years ago an earthquake killed the parents of a young man on his way into university. Before they died they pulled three orphaned triplet sisters out of the rubble and asked their son to raise them. The three girls made a promise of their own: when he turned 28, one of them would marry him. He kept to it. He sold off the family property and held on to a single house, and he spent the money on the sisters until all three of them were famous in the entertainment industry. Then they ran into a neighbor from their childhood, Dick Grand, and their attention went entirely to him. On the night of his 28th birthday party, the sisters killed him. He wakes up seven days before the party, alive, with a system attached to him that pays him rewards each time one of the three suffers over love. He decides this time he will settle it himself.
