Eight years ago, Edward Harrington, the eldest grandson of the Harrington family, fell into a coma after a car accident while rescuing his wife, Vivian Sinclair. Since then, Lady Harrington has harbored resentment toward her missing grandson and left home in anger, while the three Harrington brothers have spent eight years searching relentlessly for him. Meanwhile, Vivian Sinclair has been caring for her comatose husband in the countryside, single-handedly raising their twins—a boy and a girl—while struggling through countless hardships to afford his medical expenses.
