[30 Years old + unmarried + single + no education] Cheng Bai'an, a five-person with no money, actually traveled back to the age of 18 due to a car accident and had to take the college entrance examination again? !

Just when she was at a loss what to do, The top university student in the class and the whole grade actually asked to sit at the same table with her... I always feel like something is weird...
