Did I Travel Across Time Just to Eat Dog Food? !

A junior high school dropout who stayed at home and became a five-year-old child traveled to a parallel world in 2007 where everything was the same except for the people. There is no golden finger, no system, and no mobile phone. Fortunately, there is a computer at home, so I can barely make up for it. On the first day of time travel, I ate my parents' dog food until I was full. (The introduction is weak, please read the main text. This book is also known as "About me feeding myself with dog food after my reincarnation" and "Did I make a mistake when I traveled back to a 5-year-old child and fed myself with dog food!" In addition, the heroine will appear later)
