Summer (Sammi Cheng) is a career-oriented woman in Hong Kong metropolis. Suffered emotional trauma, was abandoned by her boyfriend who had been in love for many years, and then the stock market plummeted. She lost her job again. Desperate and desperate, she sent out the existing consortium to buy the hotels and beaches she and her cousin invested together, which is tantamount to good news for her. She immediately packed her bags and flew to Dandan Island, Malaysia, where the beach was located, to prepare for the transaction.

Who knew it never rains but it pours? Summer's cousin ran away because he couldn't repay his gambling debts, and transferred half of his beach and hotel ownership to Momocha (Richie Jen), a member of the local indigenous youth beach rescue team. In order to let more people enjoy the sunshine and joy of the beach, Momocha refused to give up his land, but the consortium preparing to buy the beach insisted on buying all the land, that is, the ownership of Momocha and the beach and hotel owned in summer, and offered an amazing price for this. She went to the court to fight for the ownership of the hotel, stayed in the hotel while waiting for the court, and they lived together for a long time.

In summer, I began to feel isolated. When I was extremely depressed, I went to the bar alone and sang loudly. It happened that Yaocha and two good friends were having a drinking party. Listening to the sad song of summer, looking at her helpless and sad eyes, a strange feeling passed through his mind, and he realized for the first time that summer also had a fragile and emotional side. Just then, there was a conflict with a local ruffian in summer. Just as she was about to be beaten, Mocha stepped forward and rescued her in time. Stubborn summer said nothing, but I felt grateful.

But the purpose of coming to Malaysia in summer is not for love. Seeing that the deadline for the acquisition is getting closer and closer, she is extremely anxious. Summer, which has always been unyielding, decided to do everything possible to let Mocha transfer land resources. To this end, she tried every means to please Mocha, but Mocha was unmoved. Inadvertently, Xia realized that Mocha's fatal wound was a woman's tear, so she made a plan and decided to make a final attempt.

In the summer, I carefully arranged to invite my girlfriend Daisy from Hong Kong from 19, and paid for a lame actor from a local artist training class as a temporary boyfriend. In the bar, a good friend fights for love, lovers and friends betray themselves, and specially invited Momo Tea to witness the whole process. She wants to impress her cold heart with her painful experience. After the play, I plan to open some tea in the summer and go back to the bar to pay for my temporary boyfriend. At this time, an amazing scene happened: in real life, Xia's ex-boyfriend suddenly appeared, hugged Daisy affectionately, and proudly announced to Xia that they had been deeply in love as early as two years ago. Only Xia was the last one to know that the real third party was actually Daisy who had been together for many years. Before leaving, Daisy pointed to the summer face and dropped a sentence: "How can you have true love and friendship if you are so arrogant and overbearing?" Hearing this, she was completely shocked. If the heavy blow of love makes people powerless, then the betrayal of friends is even worse. However, after this real and cruel scene, I didn't see any tea.

Summer really cried, so Mocha tried her best to care for her scarred heart. In the day-to-day communication, the relationship between two people has undergone subtle changes. At Summer's birthday party, Momocha carefully arranged a program for her, which made Summer feel really excited, and a specious love attack and defense war began.

But summer knows that she is a career-oriented woman, and she comes from two different worlds, so there will be no good result. But in fact, Mocha, an architect in new york, goes back to the island for a holiday every year and temporarily hides his identity because he loves summer.

The last line of defense in their hearts is about to melt under the scorching sun in Malaysia, and a beautiful true relationship is about to happen. However, at the critical moment when Momocha decided to transfer half of the equity of Shanghai Beach, Momocha angrily revealed in front of everyone that Xia was a woman with ulterior motives and playing with her feelings for personal gain. It turned out that Momocha met her temporary boyfriend in the summer by chance, and realized that the drama of winning love in the bar that day was just a scam, so she counterattacked him. The deep misunderstanding once again caused the irreconcilable contradiction between them.

Moved the true summer, and suffered an emotional blow. When she was completely disheartened by love and laziness, she packed her bags and flew back to Hong Kong sadly.

However, Momocha, who stayed in Malaysia, fell into painful thoughts and endless memories. When he learned from his friends that he misunderstood the summer because he only looked at the surface, he was even more regretful and sad. Mocha realized that summer was the love of her life, and she would take it back even if she spent her whole life. He looked everywhere in Hong Kong, and there was no news of summer. Lonely tea can only send emails to Xia every day, hoping to get her response and understanding.

Day after day, Mocha's sincerity and infatuation finally touched the summer in Tokyo. On a sunny day, summer finally returned to Dandan Island, Malaysia with a full touch and a vision for the future. A pair of lovers who have experienced ups and downs finally embrace together. They decided not to sell the shares of beaches and hotels to big consortia, but to enjoy the sunshine, waves and sweet days happily with the people on the island.
