Only one love interest dies so I don't understand what the other reviewer is talking about. The second love interest doesn't die. Maybe he is talking about the fact that he MC had a wife who died before start of the story but that doesn't count as a love interest IN THE STORY.
*shrugs* The few that did can only blame the ending
Until you get to the end, of course. The little bit of anticipation you build up in the last few novels is destroyed by Yu Wo’s classically evil Deus Ex Machina ending in just four paragraphs.
