After being reborn back to 2015 in her 18‑year‑old body, wealthy businesswoman Erin enters her son Noah’s high school as a transfer student to keep him from repeating his disastrous past. Rebellious Noah skips classes and is charmed by the manipulative Anna. Unexpectedly, Alexander, Noah’s biological father, also reincarnates. Mistaking Noah for Erin’s new lover, he constantly competes with the boy. Later, a severe peanut‑allergy accident uncovers their blood tie. Facing family lies, hidden schemes and tough exams, the three heal old wounds, resolve misunderstandings, and Noah finally earns admission to an Ivy‑League university through his own efforts.
