The husband and wife were in the house. They were not asleep yet. They only heard the weird woman humming a song that I could not understand. Koizumi suddenly stood up and walked into the house. I kept calling Koizumi to call him back. Hearing the same, kept walking, the man opened the door and brought Koizumi in. I don’t know what to do, I don’t know what Koizumi is doing inside!
