Because she drowned while jumping into a lake to save someone, beagle Song Jinjin transmigrated into a vicious supporting female character of the same name. Little dogs only do three things: eat, wreck the house, and cuddle with people. Relying on her sense of smell, Song Jinjin found her master's younger brother, Ji Laizhi, and managed to enter Saint Vili Academy. Because she was an illiterate person who didn't know many characters, she could only stay in the experimental class as a trial student. However, relying on her astonishing athletic talent and completely boundaryless enthusiasm, she made many good friends, and Song Jinjin's life was filled with more and more love. The plot is relaxing, healing, warm, and hilariously everyday.
