This isnt a romance... actually, when she says "unwanted emotions" it only makes me uncomfortable. I mean, desire is one of the most natural ways of expressing love.
Honestly, the story was interesting... up until Yui father death. For me, felt like a lot happen but hardly anything changed. Ended with both still in a relationship of supply and demand.
Somehow pitiful when u think how much pleasure both would have together with those bodies. But thats beside the point.
Overall, the journey was good for the most part but surely i didnt felt happy with this ending. Could easily trade the Romance and Yuri tags for solely Shoujo ai.
