In the meantime, Mrs. Yashiro arranges Kayo's marriage with the third son of an Osaka rice dealer, Masao, a graduate of the Tokyo Imperial University (present-day University of Tokyo), who is prepared to marry into the family to help the family business succeed. Kayo wants to leave for Tokyo to be present for Kota's return. But Mrs. Yashiro collapses from a heart attack, so Kayo reluctantly stays behind. She telephones Oshin to inform her when Kota returns to Tokyo. Oshin meets Kota when visiting Kayo's rented room to clean it. He tells Oshin not to let Kayo know that he is back in Tokyo and tells Oshin that he does not love Kayo, and that he had only used her to fill the emotional void left behind when he was not able to be with Oshin. Oshin leaves for Sakata to attend Kayo's wedding. She does not update Kayo with news about Kota for the sake of Kagaya's future. Through Kayo, Oshin meets Ryuzo Tanokura, a seemingly rich textile trader who frequents the Ginza coffee house. The third son of a prominent Saga family, Ryuzo decided to leave home for Tokyo to strike out on his own. Seven years Oshin's senior, Ryuzo falls in love with her, and the two get married despite initial opposition from both their parents.
