I have mixed feelings

Don't get me wrong i love this series but... I want to see Sam with Um together... It hurts too much as I got emotional (when they get estranged twice)... what a fate it brings them closer twice not to allow them being together and now Ur is reincarnated into some other world and even when Sam got so much powered up and cleared that trial he isn't able to do anything about it....... I want to see them get together at least in a single world...
