Kanariya wa Kago no Naka - Season 1

Student Endou Sakimi faces a severe financial crisis after a former partner betrays her, leaving her with overwhelming debt. In desperation, she approaches the operator of a 'gentleman's service' for assistance. This man confines her to a room continuously, permitting exit only to carry out assigned duties. Within this confined space, Sakimi encounters the enigmatic Fujidou Mana. Sakimi's objective becomes to sever the restraints imposed upon her and liberate both herself and Mana from a reality defined by enforced cosplay and the fulfillment of carnal demands.
