it feels like the novel the MC read is all about the sub-char & mob char misfortune and the main villain are Emma, Pat, The Royalty Duke and The High Priest.
The Duke is also a Royal both him and Emma are eligible to become Emperor.
The Priest reaction during the blessing, the priest block and try to defend the High Priest against the angry Emperor as if the High Priest is in equal footing of the Emperor.
The Mob Char “Ray” is now revealed to be much more stronger than Pat who is Main Char.
Also the fact that Ophelia in reality is superior to Emma in terms of ability, she is even superior than the Emperor since she has both Magic & Holy Power.
It feels like if Ophelia gained power she will not only ruling the kingdom but the church as well since her Holy magic power is surely equal to that of a Saint since her mother is a Saint.
The very Fact that the Novel she read is not finished and all the Main Cast feels very suspicious “like Emma trying to cause trouble to Ophelia from the very beginning”
The clues are #1 her early appearance, #2 her trying to visit Ophelia before the Banquet but gets block by Ray #3 the Dance incident #4 the Tea Party #5 Emma reaction every time the Emperor cares for Ophelia..
The reason the emperor favor Ophelia now might be due to her change of behavior starting from when she is the only one who go against the Emperor repeatedly which Emma can’t even do including all the other nobles, its more like the Emperor picked Ophelia and backed her up now as official heir to the throne. In original Novel even if the villain Ophelia is taking care of his father (and is said that she poison him) his father is still very kind to her even if she show favor over Emma.
