Last year, because of Han Yixiao's affair, she had gone to consult with Zhang Te for some information.
When Zhang Te spoke to her about Han Yixiao, he mentioned some things concerning Han Jingwen and little Qing.
Zhang Te said that Han Yixiao wasn't born mute; his vocal cords were undamaged, and despite consulting many famous doctors, Han Yixiao's inability to speak remained uncured. In the year Han Yixiao turned ten, he was almost cured by Han Jingwen. But before Han Yixiao could fully recover, Han Jingwen passed away...
It was then that Xia Wan'an learned that Han Jingwen was a doctor, Xie Lin had grown up under his wing, and Han Jingwen had a girlfriend who was eight years his junior. However, Zhang Te did not know her full name and only knew that everyone called that girlfriend little Qing... Han Jingwen and little Qing were in a mentor-apprentice relationship turned romantic.
