My Two Enemies in the World

"All encounters in the world are ordinary things" Song Qi was an ordinary doctor. On a dark and windy night, he saved a person. The man's name was Zhan Zhao, nicknamed Nan Xia. There was another person following him, named Bai Yutang, nicknamed Golden-haired Rat. One is calm and gentle, the other is open-mouthed. Song Qi originally thought that the matter was over, but the two of them refused to leave. The three of them travel together. They are jealous of each other in small matters, but depend on each other for life and death in big matters. Later, Dr. Song found out—— This didn't save one person, it caused two troubles that they couldn't get rid of.
