This was based off other spoilers I read, so my memory is imperfect and this could be incorrect but I'm fairly certain that: 1. Yes. The Emperor and Empress are in more of a business/political marriage; they respect each other and are cordial but if I remember correctly both have/had lovers on the side that they actually liked. The MC's mother was the Emperor's 'actual love', but she had that whole effect where when she died everyone forgot about her (including the Emperor). 2. Yes, the MC is the Emperor's daughter.
