When Tanner Gary was elderly and needed a bone marrow transplant, he discovered his son wasn't his biological child. Later, he found out his assistant, Hans Nolan, was actually his wife Lorry Gary's first and true love. The son was born to Hans and Lorry, and they named him Harry. In order to seize the entire Gary Group, Hans and Lorry killed Tanner, but Tanner was unexpectedly reborn and traveled back to the day before his wedding. After his rebirth, Tanner vowed to stop being a pushover and to cherish the people around him. However, his fiancée Lorry still arrogantly believed that he would remain her loyal lapdog. She first checked into a hotel with Hans, showing no remorse, and even used the upcoming wedding as a threat against Tanner. Then, at the wedding, she confessed her love to Hans, only for Tanner to expose their affair on the spot, causing the wedding to fall apart. Her family, caught in the ensuing scandal, faced a crisis and was on the brink of bankruptcy.
