Huai Chengyu has a younger brother named Huai Qiandai.
My grandfather, who was dying soon, sent his elder brother to the Song family, and he was sent to the home of an uncle who taught opera. Grandpa saw the wrong person this time. The adoptive mother is a paranoid opera lover...
Fortunately, Huai Qiandai has an ability and his identity is Qian Mengdie.
Huai Chengyu's good brother is called Li Zhi.
Corpse stitcher is an unlucky profession, but Li Zhi happened to be in it. Coincidentally, he has an ability that can complement Hua Qiandai - reading parts of other people's memories under certain circumstances...
Intention: Maybe in a dream, someone is helping you untie your knot...
