In Tokyo, on a corner exists Takano Pharmacy. The owner is widow Ginko Takano (Sayuri Yoshinaga) who lost her husband a long time ago.

The day before the wedding, Ginko receives a wedding invitation that she mailed to her younger brother. The invitation was returned to sender. In Osaka, Ginko's younger brother Tetsuro (Tsurube Shofukutei) works as an actor and is an alcoholic. Tetsuro has been estranged from the family since he made a drunken scene at Ginko's husband's 13th death anniversary.

Shohei then tells them, "I will cut off all relations with Tetsuro ..."
