Shen Ran and Jiang Zhi met and fell in love, but their happiness didn't last. Shen Ran got cancer and didn't want to drag Jiang Zhi down, so he decided to break up with her. During their breakup, they argued, and Jiang Zhi was in a car accident that left her with no memory of Shen Ran. He never told her who he was, and quietly left. In the hundred days before Shen Ran left, he personally planted a sea of gardenias for Jiang Zhi. Shen Ran thought that as long as Jiang Zhi was happy, he would have no regrets. A year later, Jiang Zhi came to the flower field and remembered Shen Ran. She buried this love, which had come too late, deep in her heart and carried on with her life alongside her current boyfriend. She didn't want to hurt him; after all, they'd been together for so long and had developed feelings for each other. So Jiang Zhi and Jiang Nanyu quietly continued their life together.
Theme: Be brave and pursue what you want
I'm just looking forward to the plot behind it.
