Just like the name of the movie "Old buffalo and young grass", the old man is over 50 years old but his health is extremely good, especially his golden bird, this is the dream of many men in their old age. . Todaku was old and weak and lived alone with no one to take care of him. He decided to call the home care center and asked an employee of the company to come and take care of him. He was surprised and happy to see him. Seeing that the person he was about to share the house with was a beautiful and gentle girl in her twenties, of course there had to be a reason why he felt so happy.
