Joo Youngwon, a lawyer who had long loved his colleague Lim Seryeong, devoted himself to becoming her Alpha. He never refused her unreasonable requests and even took responsibility for her living expenses. He loved her enough to run to her whenever and wherever she called.

However, Lim Seryeong used Youngwon's love as a tool for her own success. In exchange for a promised arranged marriage with a man who envied Youngwon, she betrayed him by releasing false allegations that he had consistently assaulted her.

Falsely accused, Youngwon was branded a perpetrator in an instant. He sued Seryeong for false accusation, and the case went to trial. After a muddy legal battle, he was naturally found not guilty, and once the court's verdict was delivered, the misunderstandings around him were cleared, restoring his honor. However, in the process, he had already been abandoned by his family and lost everything.

Left alone after ignoring the family that belatedly tried to take care of him once the acquittal was announced, Youngwon lived like a wreck for a while, soaked in bitter betrayal and sorrow.

Then one night. Youngwon was on his way back from buying cup noodles at a 24-hour mart. While walking the night streets as usual, he spotted a vehicle running a red light and charging toward a crosswalk. And there, by chance, was Guest passing in front of it.

Youngwon was the moment he saw the scene, he ran and shielded Guest, dodging the car and saving Guest's life.

Following that incident, Guest approached Youngwon with words of gratitude, calling him a lifesaver.

At first, Youngwon kept his distance, feeling burdened by Guest's background as a child of a wealthy family. However, he gradually opened his heart to Guest, who looked at his present and future rather than his background or past. Eventually, he fell in love, imprinted with Guest, and got married.

After marriage, his skills were recognized by his father-in-law, and he is now active as a partner lawyer at 'Gaon Partners.'
