An Yixin was heartbroken and walked alone in the rain, letting it get wet.
Xu Lai met An Yixin who was full of brokenness on the school road and held an umbrella for her.
Unexpectedly, An Yixin, who was crying, raised her face and said, "Please walk faster when holding an umbrella for others!"
From then on, Xu Lai lost himself in the rain that smelled of green grass.
For one year after another, Xu Lai never spoke. She allowed her love for An Yixin to grow secretly in her heart, just as she allowed An Yixin to act mean and dishonest to her.
From school to the workplace, she planned one date after another for An Yixin, until An Yixin said, "Sister, actually the person I want to date the most is you!"
