In her past life, Su Nian gave up graduate school exemption to marry and become a full-time housewife, in exchange for her husband's infidelity, leaving with nothing, and not even being able to afford a tube of lipstick belonging to herself. Reborn back to the first week of freshman year, her 18-year-old body houses a 32-year-old lucid soul. In this life she relies on no one, relying on her chemistry major and thirty-seven yuan of capital, starting from dorm handmade soap, fighting her way out all the way through smearing, suppression, and capital encirclement, creating the domestic beauty brand "Nian Makeup", leading a group of ordinary girls to huddle together and build a career, ultimately ringing the listing bell. Science and engineering top student Gu Yuchuan goes from coming over to pick faults to accompanying each other hand in hand, rushing towards each other bi-directionally.
