Author's Comments- This story consists of short chapters that were inspired by a video or a fanart found online a while back. At the beginning of some or most of the chapters I will state what inspired that particular chapter.
There was a man named Kenzo Tenma who lived in an apartment building in Berkeley, California, which was called K Flats. He's known a boy named Johan and his twin sister Nina since the day after they were born. Their mother was named Anna.
He knew her since the day she moved into the apartment building, which was a month before the children were born. Her apartment was next to his on the left. After three weeks of getting to know each other they became close, forming a platonic relationship.
After the twins turned five Kenzo offered to watch them when he was free, which were on the weekends since he's a high school teacher. Anna took the offer. It became routine in a very short time. He's done it for five years.
