They meet on the bridge while looking at the stars on summer nights, playing hide and seek during the day, and lying on the grass to watch the floating clouds in their spare time....... , Sitting on the ridge of the field reading and talking, looking at the hazy field in the drizzle, the swallows who both returned、、、 when Zhixin met Zhiyun again, she was already the mother of the child. But she was also a mad woman, alone with her son, but she didn't know her. She doesn't know who her son is, and she doesn't know the acquaintance she met.
