Before Dawn (Ling Yuan Fanfiction)

Ling Yuan's requirements for a partner were simple. Clean, upright, and good to him. Or any two out of the three would do. Lin Nianchu was good in the latter two respects, even if she wasn't much for tidying up, and that was more than enough for Ling Yuan. Unfortunately, he couldn't hold on to this wonderful partner forever. So something inside him snapped. He planned to spend the rest of his life devoted to the medical profession he loved, but then someone barged into his life without a care in the world. This time, just one out of the three would be enough. Ling Yuan is the bottom. P.S. The author knows nothing about medicine, so don't use the medical content in this story as a reference.
