Timeless is an extension of the entire series of fan fiction.
The main characters are Fu Chi and an original male protagonist. There is an implicit CP line, but no real progress.
The overall context will not conflict with any series or extras of Timeless.
Except for the epilogue of the last chapter, the whole text is very warm and sweet, so you can eat it with confidence.
Intention: We all have reason that is higher than rational judgment, because we all come from Shura field
