Ye Lengyue, who grew up abroad, suddenly learned a piece of news one day:
Her sister died.
In fact, the two of them had nothing in common, and they had never even met each other a few times. The only thing they had left was a photo of them together when they were young.
But what puzzled her was that her sister was obviously better than herself, but she came to a strange city to live alone at the age of twelve.
For a period of time after learning the news, she somehow missed her sister more and more intensely, even though the person she remembered could no longer clearly see her face.
After tossing and turning, she made a decision full of unknowns.
She decided to come alone to the city where her sister lived, and follow the traces left by her sister until she knew everything about her sister.
But what she didn't expect was that this decision would lead her to encounter incredible things, even traveling through time and space.
Is... Is there really a way to save my sister? !
Intention: feeling of longing
