The movie "Little Milk Dog Little Wolf Dog"

A big online movie with elements of love, fantasy, adorable pet, etc., mainly tells the story of Shen Han, a gentle and kind veterinarian, who runs a pet hospital and adopts four different breeds of dogs. One night, her fiance Hu Junjie forced her to marry Shen Han and tried to steal money. Deeply disgusted, Shen Han resisted and escaped. He went back to the pet hospital and cried and complained to the dogs. He never wanted to wake up, but these four dogs became four handsome naked men! In order to accommodate four boys and hide Hu Junjie and his parents, Shen Han made a careful plan. Unexpectedly, it was self-defeating, full of loopholes and made many jokes.
