Review Detail of Mushy_Avocados in To Rise Again in the Apocalypse [BL]

At the beginning of the story I was excited to read it because it was interesting for me that a cultivator got reincarnated into an apocalypse world and how the sister also got reincarnated. I also liked how they were such a close knit family and how he got to experience what having a warm family is.But I really can't stand these kinds of misunderstandings with the ml. I know some people are fine with with how it is and I read some other reviews saying how the misunderstanding is cleared up at chapter 60 but I don't understand how the mc acts like such an air head around him. If you like your sister why would you be OK with her being with a guy that blackmails you and gives her a greenhat? It also kinda feels like he completely skips over the fact that he sexualy harassed him in the past before and continues to do so. It just feels like he's enabling him. They seem way too forgiving to me for this kind of situation. There is no logic in the sister's decision of letting the person who gave her a greenhat back into their lives. He led her on for like 5 years and was also one of the reasons for the mc's death in the future? Also the way the ml acts so shamelessly with the mc is frustrating and uncomfortable.
