Lu Xiaolu and Xylophone are very good friends. They go to and from school just like the most ordinary children, living a life of two things at school and home.
But one day, a young man from another world suddenly came to Xylophone's room, and Xylophone actually followed him through time to that world!

Strictly speaking, it is not cp-free, but the protagonists are a pair of good sisters and they will each be with the person they like.
I borrowed some background settings from my other article "Velvet Flower" (although that article has not introduced the world line in detail yet, but it does not affect it), but the two articles are not in the same world, they are equivalent to parallel time and space.
Since I dare to release it, the full text must have been saved. Don't worry, the cover image was drawn on a whim_(:з)∠)_
Concept: After the hero travels through time, how sad will it be for the friends who stayed in the original world?
