i thought that when yueru went to beg linger, yr asked for le to either stop hurting xy and be with him, or leave xy alone so yr can heal his heart. sounds reasonable. le just couldn't do one or the other.
sure xy and yr bicker back and forth, but they enjoyed doing that. during the journey, they were with each other all the time, therefore it is sound to assume that they can live with each other. they laugh and they have fun.
yes, xy wanted to see and be with le but i think that's because he was NOT. if le didnot died and live with xy, that would be one miserable life for him. is it just me or does she not smile at his attempts to joke and doesn't notice when he tried to get a smile from her? there were a few parts when he does joke, that she chastised him like a child...
as for the one scene of xy reminscing about yr, there's rumors that there were more similar scenes but just edited out to fit the episodes. and i bet on those cold winter days and nights, xy would miss yr more than le. le and xy have what, one night and a few days to remember but xy and yr have so much more.
i officially stopped at episode 25 (while siblings finished the series) but i cried more watching yr spilled her emotions and thoughts out to #7 than seeing the clip of le's death.
