Five years ago, Gu Bisheng was framed by her own sister and lost her virginity, then sent to a psychiatric hospital by her biological mother. Five years later, she makes a domineering return from the asylum, taking her sister's place to marry Fu Xizhou, the second young master of the Fu family who is rumored to be disabled and sickly. Thinking it was merely a nominal wedding-blessing transaction, she unexpectedly finds the dynamic changing completely after marriage as she uses her miraculous skills to cure the CEO's hidden illness; with her hidden identities dropping, she turns out to be the top university president and medical sage! Fu Xizhou tears up the divorce agreement, "Principal Gu, you want to run after using me up?" When the owner of that mysterious jade thumb ring from five years ago appears and the sealed-up truth is uncovered, the austere second young master transforms into a wife-protecting maniac, accompanying her to send those debtors into hell one by one!
