In order to take care of her father, Garret, who injured his leg, 42-year-old Elara has been suppressing her talent in sportbike racing for 20 years, working as a postal carrier (UPS Mail Carrier) during the day and working part-time at night to earn money. An accident on her birthday night caused her to have a relationship with the 31-year-old gang boss and champion driver Asterion. The two had a misunderstanding over money and thought they would never see each other again, but they got deeper and deeper into each other through unexpected reunions. When Elara found out she was pregnant with triplets, she wanted to take the responsibility alone because of her age, financial pressure and Asterion's dangerous status. After Asterion learned the truth, he insisted on taking responsibility, and the two finally signed a secret marriage agreement: living together before the child was born, Elara could still work, and if she wanted to leave after the child was born, Asterion must let her go free. The marriage that was originally just for children has gradually deteriorated in the process of cohabitation, protection and escalating intimacy. At the same time, Elara entered the West Coast Racing Academy (WCRA) and reconnected with her riding talent that had been buried for twenty years from the most ordinary pit assistant position. She has proven herself in out-of-control accidents, Coach Certification Exams, and large-scale projects.
