My name is Reiko Shiratori! The Movie

Storyline

Reiko and Tetsuya continue to live together. Reiko, who was informed by Kyoko that she was engaged to Takada, pretended not to be interested in her marriage, but in her heart, she wanted to marry Tetsuya. Tetsuya, unable to see through Reiko's true feelings, replies, "We shouldn't think about marriage until we're both adults and can live on our own." Meanwhile, Reiko's father, Shotaro, is stricken with cancer and receives a call that he has six months to live. In order to fulfill her father's wish, "I wanted to see Reiko as a bride while I was still alive," Reiko asked Tetsuya to marry him, and Tetsuya hesitated but accepted. However, Shotaro's doctor informs him that the cancer was misdiagnosed. While Reiko is relieved, she does not want to cancel her marriage to Tetsuya, so she proceeds with her wedding preparations without informing the people around her.
