She maintains lively correspondence with her younger sister Erzsi, who remains in Budapest, working as a music teacher.

Presently, Paula wields a significant influence over Erzsi, persuading her to dye her hair and gifting her a dress.

On the other hand, Erzsi discloses to Paula in one of their meetings her affection for opera singer Viktor Csermlényi and her deep-rooted passion for music.

Despite Viktor's insistence that, at 71, he no longer possesses the same vocal prowess, Erzsi finds it disheartening to witness his decline.

Incensed by Erzsi's absence during the opera, her students intentionally perform poorly during a recital in front of the school principal.

Jealous and hurt, Erzsi initially contemplates canceling a planned dinner on Thursday but ultimately relents.

Subsequently, her maid Mousey expresses concern to Giza, suspecting Erzsi may be on the brink of a nervous breakdown.

Despite Giza's attempts to persuade her to relocate, Erzsi adamantly refuses, preferring to spend her final days in Budapest.

In these missives, she recounts an encounter with Viktor and Paula during a meal, during which she succumbed to rage, overturning the tableware, and leaving abruptly.

Erzsi confesses her love for Viktor to Giza, entreating assistance in organizing a concert tour for him across the Federal Republic.

Following days of lethargy spent in bed, composing unfinished letters, Erzsi consumes an overdose of sleeping pills.
