A placement test, an unexpected encounter, Mo Chuxiao never thought that the young man in white would become the one she looked up to when she was a student. She looked up to his silence and his calmness, but little did she know that this young man, who was more mature and steady than his peers, had already closed his heart a few years ago. But she used the persistence and willfulness of that era to open his heart bit by bit. She saw his panic when he was calm, and she also saw the pain after he calmed down. In this way, his secret was seen through by her with her persistence and admiration, until the last secret, the panicked person, became her.
