The Year of the Tiger, during the COVID-19 pandemic. The Grain Rain season.
The dashing young writer Tang Yimin travels to Fengyan Island to experience life. There, he meets Xia Lian, the beautiful young owner of a guesthouse. Tang Yimin, who yearns for a pastoral life and suffers from mild depression, gradually recovers both physically and mentally during the vacation Xia Lian has carefully arranged for him, leaving his old gloom behind. Before he knows it, Tang Yimin has fallen for this bewitching, affectionate island girl.
The two go beachcombing, cook together, go on blind dates, travel together, and celebrate their love together. At the same time, Tang Yimin happens to discover that Xia Lian is no ordinary woman.
Everyone in Xia Lian's family has a story.
One day, Tang Yimin is caught up in a bizarre kidnapping. After surviving the ordeal, he is certain he has found true love.
The bright moon hangs overhead, and the waves murmur softly. Hand in hand, the two stroll along the beach. The soft sand feels like a kitten licking the soles of Tang Yimin's feet.
With the romantic, beautiful blue tears as their witness, Tang Yimin gathers his courage and proposes to Xia Lian.
Gazing at the enormous diamond ring in Tang Yimin's hand, Xia Lian's eyes fill with tears even as she smiles radiantly. She says, "A diamond ring this big... it isn't fake, is it?"
Happiness seems within reach.
But just as their grand wedding begins, everything suddenly takes a turn...
In the end, a long letter reveals the truth behind several murders.
