The story begins in early summer but ends in hot summer
Su Mumu's family was broken. Cheng Bai met Su Mumu when he was a sophomore in high school. They fell in love at first sight, but refused to disturb her too much. He could only look at her quietly every day. Su Mumu's smile was like a little sun, lighting up Cheng Bai's whole world. Cheng Bai confessed to Su Mumu and promised to take her away from the broken home. Su Mumu signed a love contract with him. Cheng Bairuoti broke up and gave Su Mumu 400,000. In turn, Su Mumu gave her 400,000.
Unfortunately, Cheng Bai fell ill and had no choice but to break up with Su Mumu. Su Mumu wanted to pay 400,000 to keep Cheng Bai from breaking up, but Cheng Bai was determined to leave. He put 400,000 into Su Mumu's bank card from the hospital bed. Su Mumu was heartbroken.
Later, Cheng Bai's friend Xu Jing and Su Mumu's friend Jiang Xiaolin told Su Mumu the truth. Su Mumu rushed to the hospital quickly, but it was still a step too late. Cheng Bai lost his breath the moment she opened the door. Su Mumu knelt beside the hospital bed and cried bitterly.
In the end, Su Mumu took a walk on the street at night, with the summer wind blowing. It was the same as taking a late class in her sophomore year of high school, except that Cheng Bai was missing on the left hand side closest to her heart.
Intention: Love will not pass or disappear with time
