The accident happened on a quiet summer day. Suddenly the fire alarm went off and I jumped out of bed and rushed out of the room. At that time when smoke was flying in the corridor of the apartment and I was coughing, the next married woman, Yuko, also came out of the room. Perhaps in a hurry, Yuko-san was wearing her underwear, and unexpectedly she was wearing transparent underwear. In the end, the fire was quickly extinguished and all was well.
