Tsubasa visited his father-in-law, who had been divorced for a long time and lived a lonely life alone. To his father-in-law, who had been drowning in alcohol and lived a self-depraved life, Tsubasa repeatedly offered to take care of his late father. However, the father-in-law is attracted to the shiny body of the collar which becomes dew sometimes, and attacks the collar forcefully! It is a bewildered collar, but gradually the color is drawn out to the adhesion act of the father-in-law.
