1. Marriage first, then love, it starts with transaction and gets stuck in sincerity. In order to save her bankrupt family, Su Qingyan was forced to marry Gu Yanchen, the business emperor of Shanghai; in order to stabilize his power, he needed a "Mrs. Gu" to keep everyone quiet. The cold agreement on the wedding night drew a clear line, but it couldn't stop the heart-warming temptation of getting along day and night - he defended her strongly at the dinner, silently supported her in difficulties, and was paranoid about staying when she wanted to escape. From each getting what he wants to having a deep love, this game of marriage first and love later finally caused the two of them to fall into the whirlpool of love.
