During her third year of college, Su Yunyun begins a new chapter in her life after encountering two important men at the start of term: one is her childhood betrothed, newly returned from military service, and the other is her biological older brother, with whom she has never been in contact. After initially butting heads, they gradually develop an unbreakable bond as lovers. Together, they take on the forces of evil, crack down on an underground organ-trafficking ring, and protect the stability and safety of society. Along the way, they find family, love, and friendship.
