Our couple, who are in their third year of marriage, bought this second-hand condominium after consulting with them and taking a 35-year loan after consulting with them after my promotion to section chief. It was a happy new life, but there was only one problem. It's about Takemaru, a resident who lives upstairs and looks like DQN. One day, we finally became unbearable, and the couple went upstairs to the DQN room of a person named Takemaru to protest the noise problem.
