Aria, who was financially drained by the scumbag Liam and tragically died in a hospital ward, is reborn, returning to her senior year of high school. She severs the toxic relationship, takes out her savings, and buys out the tutoring time of Kael, the school's impoverished academic genius. Kael, who appears down-and-out, is actually the hidden heir to a top conglomerate, having obsessively and secretly loved Aria for years. From then on, Kael protects her every step of the way, helping her escape the scumbag's clutches, crushing the money laundering and false accusation traps set by her opponents in collusion with outsiders, and eliminating her business rivals. Aria establishes a tech company and rises to the top of the business world. The two resolve all deceptions and misunderstandings, marry in front of countless witnesses, and, with a top-tier business empire in their hands, achieve a perfect, mutually devoted love.
