Misidentification? Seems Like an Old Friend

In the ninth year of the Republic of China, Tongzhen Pier. Shen Jingshu mistakenly recognized a young man wearing a gray cloth gown as her younger brother. That was the first time she met Gu Mingyuan. He is the teacher who came to set up a new school, and she is the taciturn daughter of the Shen family. When the loquats were ripe, he picked them for her to eat; when it rained, he took out the umbrella she dropped on the pier - he kept it for several months and never returned it. She asked why. He said he was afraid of embarrassing you. A fate that began with misunderstanding, a silent and affectionate era of subtlety.
