While out on their rounds one day, Tsugumi and Hisui learn of the existance of a book written by a prostitute from Yokohama's redlight district. Hisui seems especially desperate to get his hands on this book and when Tsugumi learns the reason why she becomes determined to help him. When Tsugumi discovers that Shiginuma Shouko, wife of the shady owner of the Nachtigal dance hall, she finds herself stepping back into potentially dangerous territory alone.
Please don't treat me 
like I'm younger than you.
.كفّي عن معاملتي وكأنّي أصغر منك رجاءً
Bitte behandle mich nicht mehr so,
als wäre ich jünger als du.
No me trates como si fuera menor que tú.
No me trates como si fuera más pequeño.
Arrête de me traiter
comme un gamin !
Smettila di trattarmi 
come se fossi più piccolo di te.
Pare de me tratar como
se fosse mais jovem.
Хватит считать меня маленьким.
