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.
Being a sheltered young lady,
you may not be aware of this,
،كونك آنسة محمية

Tal vez no lo sepas porque
te protegieron hasta ahora,
