I watched Mu Fusheng's "In the Dust of the World" some time ago, it was very interesting! I happened to have my teeth treated some time ago, and I thought what an honor it would be to have a dentist like Ai Jingchu treat my teeth! Therefore, with a dental background and my own YY, I present a relaxing love story to everyone. This is not strictly a fanfic, but in order to pay tribute to "In the Dust of the World", a little bit of relevant background is also "stolen". In short, it is a different article.
