Tang Wei, a modern ordinary social creature, was accidentally bound by a mysterious existence called the "merit system" and was forced to embark on an infinite journey of time travel. Her mission is to travel to the worlds of various classic film and television dramas, become a female supporting character (or an important female character) with a tragic fate, and obtain "merit points" by changing her original tragic ending, making up for her regrets, and doing good deeds. However, the system informed you at the beginning that if you want to completely change your destiny and get rid of the crisis of obliteration, you need sky-high merit. What's even more outrageous is that this merit is actually a "loan" model, allowing her to work all the way and pay off her debts, and the time travel will never end.
