It's probably a story about the love-hate entanglement between ABO Star and a "rich family" who was born and passed away.
As expected, the heroine is a loli, and she likes to pretend to be A. Before the pregnancy, she was an overworked scientist. Her current wish is to specialize in mechanics and make money to buy land and live a retirement life early (8 years old)
