One day, Seiji receives an odd request from Kounosuke to look into the background of a seaweed wholesaler named Hansuke that he is on good terms with. Stylish and dashing, Hansuke is a ladies man who has a talent for business despite his age and his seaweed wholesale shop has been very successful, but Kounosuke is suspicious of his unusual generosity towards him believing that Hansuke has ulterior motives. Seiji is unable to find out anything unusual about Hansuke, but while out on a boating trip he notices that Hansuke has an odd reaction to the kiseru that Goi inhabits. What kind of past connection do Goi and Hansuke have?
But nobody knows anything 
about his background.
.لكن لا يعرف أحد شيئًا عن ماضيه
Aber niemand weiß etwas über ihn.
Pero nadie sabe nada sobre su pasado.
Pero nadie sabe nada sobre su pasado.
Mais personne ne sait
qui il est vraiment.
Però nessuno conosce la sua identità.
Mas ninguém sabe nada sobre ele.
Только вот... никто не знает, 
что было до этого.
