The sweet romance that blossoms over time between the heroine and her younger uncle-in-law, now her husband, faces a clash of identity and ethics when the original wife returns. She was originally the eldest son's wife in the Xiao family, married to Xiao Jingrui. When Xiao Jingrui went missing, the family sought to preserve the eldest branch's lineage by invoking the custom of one man marrying wives on behalf of both branches. She thus became the second branch's Xiao Jingheng's nominal wife, though he was her younger uncle-in-law.
