It centers on the sister-brother love between Shen Qingzhou and Lu Shixing, interspersed with the dilemmas and breakdowns of Wu Mei on the 28th floor of Yunsong in the workplace, native family and intimate relationships. The main emotional line is "from self-defense to bravery and sincerity" - Shen Qingzhou goes from using teasing to cover up his true feelings, to facing his inner fears and handing over his true feelings; Lu Shixing goes from hiding his identity to test, to tearing off the disguise and loving each other equally. The five people support each other, break the world's prejudice against women, and complete self-salvation.
