Lin Xinpo and Xia Xiaonuo, two ordinary twin middle school students in the 21st century. Their parents' divorce caused them to grow up in different environments.
Lin Xinpo is lively, cheerful, naughty and cute, like the scorching summer sun; Xia Xiaonuo is introverted and shy, but has a caring heart like the bright moonlight.
Meteors drag their long tails across the night sky. Time travel, this familiar and unfamiliar term, changed their ordinary lives.
The different fates of the twins, the darkness and sorrow of the big family. Two girls, Atobe Ruoxi and Shiwuye Mulyu, live their own lives in light and darkness. When the two met again, they were just strangers.
With more than ten years of blood ties and more than ten years of friendship, when they learn that the other person is the "her" they have been looking for for many years, can their fate change?
She is a rich young lady born with a halo, a little princess who is loved by thousands of people. Her beloved daughter's parents and loving sister's brother are her eternal support.
She was an abandoned illegitimate daughter, and her mother's last wish before her death was for her to return to her father. Training as a killer since childhood made her more withdrawn.
Mu Liu on the 15th Night: I am no longer the original me. I have an empty shell and my soul is no longer clean.
Atobe Ruoxi: No matter what, you will always be Xiaonuo, my good sister... I'm sorry, if I had to do it all over again, I would never let go of your hand!
