After Being Reborn with My Childhood Sweetheart, He Pursued the Class Beauty, While I Was Pampered by a Business Tycoon

From the back cover

After a car accident, Amber and Sean are reborn on the day they fill out their college applications. Sean, who once regretted sacrificing four years for her, follows Rose, the prom queen, to an out-of-state university, while Amber stays in her hometown. Ten years later, Sean has become a rising star and is engaged to Rose, and at their high school reunion he mocks Amber's simple life, boasting that the ring he bought could have been hers.

Amber remains unfazed. When Rose spills beer on her own expensive clothes and accuses Amber of jealousy, the tension rises. Then Luke, the business tycoon, arrives late and wraps his arm around Amber's waist, announcing that his pregnant wife hopes no one will smoke indoors. Sean, always composed, visibly panics, realizing Amber has not been holding a grudge after all.
