In her past life, biomedical prodigy Celeste lost her hard-earned academic placement to Vivian, the adopted daughter, wasting eighteen years of her potential. Her lung-cancer drug Stella Core, developed too late, caused severe side effects in trials, and she bore the blame alone. Reborn to 2008, on the day she meets her biological family, Celeste abandons the pursuit of their favor and devotes herself to science. She scores perfectly on exams—only to be accused of cheating. In the retest, she solves a problem that stumps top researchers, earning a place at the institute. Meanwhile Vivian, fearing replacement, fails her music exam, spreads rumors with Owen, and steals Celeste's data—but is exposed. Celeste reveals the truth of their past lives, and Vivian finally awakens. Four years later, Celeste becomes institute director, leading everyone toward a brighter future.
