Although she is called a tall mansion, she is an ordinary family that lives on low levels, but thanks to her husband's hard work, Rima is able to live in this lush green town, and spends her days with a genuinely fulfilling attitude. From now on, we are going to build a happy family together, or rather, the three of us... However, one day, after taking out the trash in the wrong way, he was caught by mothers on the upper floors who live in the same apartment building.
