Twenty days before the wedding, Jiang Ning followed her fiancé He Chen and his friends into the mountains for a camping trip. When drawing lots for tents, He Chen and his childhood friend Qin Shu ended up sharing a double tent, while Jiang Ning was left alone in a leaky tent and mocked by his friends in a group chat, along the way coming across names they carved in their youth. As a torrential rain approached, He Chen actually made a feverish Jiang Ning hike down the mountain in the rain to fetch clothes for Qin Shu. Completely heartbroken, Jiang Ning canceled her campsite booking, returned to the bridal home, cleared out all memories including wedding photos and rings, and resolutely broke up. Afterward, He Chen suddenly came to his senses and tried frantically to win her back, but on the original wedding day, Jiang Ning completely left to head south and start a new life.
