I agree. Many get mad at male leads due to previous lives. One should take into account all the differences. While they are the same person, they are technically different too. As for the spirit thing.. I’m not sure why, maybe we will find out later?
Or perhaps due to her new determination after experiencing what happened in her old life, it made it so she was able to more openly converse and see spirits? Since she stopped being extremely pessimistic when she went back in time, that might be why.. But that’s just my hypothesis.

Every one says that the male lead was bad in the previous life and now he is falling in love with the female lead after she got the power. That's not right. Everyone needs understand that what happened between them was not love marriage but arranged marriage. Not only the girl lives with someone new and practically a stranger its same for the boy as well. He did not have a chance to know her before marriage and after marriage she refused to touch her own child and did not make any effort to know her husband or about thier family. Not every person will be a hero who will save the damsel in distress. Moreover the FL was really pessamestic in her last life. If you don't say that you are in pain others will not know. I understand that the way she was because of her maternal family. But then blaming the Male lead for not caring the female lead in the previous life is not right. They were in the same boat. Moreover she was the same person and same body in last life as we. Why didn't the spirit contact her in last life and only in this one? Something was not right in her last life.
