Confusing

I know I am not the only one. The translation is a little funny and the panels are either cut off or the artist really rushed things. It could have been interesting with a better edit of the plot. It was confusing and doesn't have a fixed direction. So all I can say is that is that. Get if for what it is, literally. And if anyone is also confused about the ending, I will state my own opinion and interpretation of it.

Charles is a really kind guy who would sacrifice his life for those who need him. One of them happened to be Franco. When the old guy pushed him down the cliff (also let us note how bizarre this part was because it is too random and sudden), he was transmigrated to the past, or specifically the previous life where Mu once saved him. It's an open ending from there.
