I actually felt really sad about the two of them being victims and then that sudden flup where in the it implies Yui took the role of 'Nii-chan'. I thought it was the end, I didn't want anything left to be unanswered so half sad half happy that it'll continue.
In terms of people saying how Harada made it romanticized, do think again. If it was because of Yui professing his love for 'nii-chan' made it seem so, it ain't really. It's actually realistic. I also love how Harada added about the society, views, what should be and what's 'nornal'. The world can be fucked up, it's not like they ended up together anyways.
