Three years into marriage, Rei believes her relationship with her husband is strong, but his recent coldness troubles her. She confides in her father-in-law and discovers that her husband has been cheating. Deeply hurt by his unapologetic attitude, she runs out into the rain while her father-in-law repeatedly apologizes for his son. He follows with an umbrella and a comforting hand, saying he cannot abandon someone who has also been betrayed. Overcome with emotion, Rei kisses him, and the two sink into a forbidden affair under the same roof.
