Mai is not working well with her weak and sick husband. I couldn't say that my husband, who wasn't feeling well, wanted a child, so I was spending my days in agony. One day, on the train that takes her husband to the hospital, she encounters the first lewdness in her life. I can't show what I didn't do in front of my husband. Mai desperately resists with a body that is rigid in fear, but that weak resistance further incites lewdness and escalate the act.
