Vivian Bennett had spent her entire life building a vast family fortune, only to watch helplessly as her son, Ethan, blinded by love, squandered the family estate and ultimately jumped to his death. When she opened her eyes again, she had unexpectedly returned to 2005 and was restored to the appearance of an eighteen-year-old, and at that very moment, Ethan was also exactly eighteen. In order to stop her son from repeating the same mistakes and to make up for the regret of having dropped out of school back then, Vivian simply went back to high school and became her son's classmate. Just as she was exposing Vesper's lies on one hand and forcing Ethan to study again on the other, Caelan—the lover she had once missed—also reappeared in the form of an eighteen-year-old and entered the same school. As they spent more time together, the truth hidden for many years gradually came to light: Caelan was Ethan's biological father, and their separation back then had not been a betrayal, but the result of family interference and misunderstanding. Facing Vesper's schemes, campus rumors, the control of the Viremont family, and the plots targeting Ethan's future, the three of them went from probing each other and arguing to standing side by side and protecting one another. Ethan also grew from a truant, rebellious teenager addicted to romance into a graduate who studied seriously, made the Honor Roll, and earned the favor of Southern University with his sprinting talent.
