Misesu Shinderera

Mizuho Kayama lives with her husband Yasuyuki and her mother-in-law Ryoko , who bullies her constantly over her failure to produce a grandchild. When her pet Java sparrow escapes from the house, Mizuho welcomes the chance to follow it and tracks her errant pet down to a local park. There, she finds that the bird had flown to Mitsuru Horii, a handsome artist with whom Mizuho soon begins a torrid affair.
