Story of the Apartment I Used to Live In ⑤ The End

In the end, I never found out what happened or what it was. However, no one moved in next door until I left that apartment. I lived there for about 10 years without any incidents, but one day, a 'thump' sound started coming from the apartment above. It sounded like a small child jumping from the height of a bed. 'Maybe someone new moved in upstairs? The kid must be excited in their new place.' I thought fondly and went to sleep that day. But from that day on, the sound started every night around midnight, always the same. I was starting to get annoyed, but I thought it would be childish to yell at a kid, so I decided to have the real estate agent subtly pass on a message. The next day, I called the real estate agent. When I explained the situation, they said, 'No one has moved into the apartment upstairs.' 'What?' My blood ran cold. 'This is bad.' I don't know why, but I felt that way. In the end, I moved out as if I were running away.
