A chance locked room - a married woman doctor and patient

Nozomi is her husband and her wife, who works as a doctor herself. One day, a young man named Manabu, who collapsed from overwork, was brought to the public. As Nozomi supports Manabu, who is still difficult to walk alone, she takes the elevator!! The elevator suddenly stops suddenly. No one responds when I call for help. Then, Manabu, who was in close contact with the beautiful Nozomi in a small, closed room, was unable to contain her excitement and hugged Nozomi... Since then, the two of them have accidentally hid themselves more and more in a small, closed room...
