The previous owner had left without emptying the house. Buying a house in France as a korean

Various stories experienced while buying a house in France. The day before signing, I visited the new house I was going to move into. Since the final house sale documents were not yet signed, the house was being emptied. The day before signing the house sale documents, I visited the house, which was being emptied, and it was difficult to confirm if it was properly vacated. I thought, 'Nothing will go wrong, right?' I hid my anxiety for a moment and signed the house sale documents. But after signing, I found that the previous owner had left without fully emptying the house. The traces of the previous owner all over the house made me angry. They even left their used trash can.
The first renovation space in our house is the small red bathroom. The bathroom drainage was buried inside the house... After realizing the bathroom was leaking, I hurriedly connected the drainage to the city sewer.
One year after moving in... the water bill still hasn't arrived? The gas and electricity bills are coming in, but... Why not the water bill???
Let me share with you the story of my move to France.
