Thats one of the point as well maybe but from what we witnessed,Johannes doesnt seem to be swayed by his personal feelings or whatnot, he seem to be wise too.
I didnt comprehend it clearly from the middled chapters maybe but Johannes has conditions and wisely chosed the heir, one of it is they has to be an outsider who knows nothing and Johannes has to be the one to guide them personally so there wont be any crisis of thoughts in the heirs head,
Johannes didnt just picked up random child
If yalls thinkins its bc she looks like the past empress, i wont have anything againts that but if thats the case too im sure its just that *cries

Im just guessing when I said Johannes likes the previous empress because of that scene where he was staring at the portrait. But i cant rule out the possibility that one of the reasons why he chose shuli, aside from the fact that he wanted someone to act as a temporary head to guide jeremy, is because she looked so much like the previous empress.
It all makes sense, why did I not see this??Gosh it never occured to me that Johannes HAS FEELINGS FOR THE EMPRESS. Thats partly the reason why he took shuli as his wife- cause she looks like the empress and he has feelings for the empress Σ(  ̄□ ̄||)
