It's quite common since the setting is in a kingdom so a fight for the throne is inevitable. Manga readers will eventually will come to know Alberu's secrets as the story will progress so keep an eye on him. There will be a lot of characters to look forward to here. ^^ ENJOY! You could also read the light novel if you want to catch up.^^v
There's also a lot of people who likes hetero ship from what I've seen in the commen section in the novel. It's just BL really just dominates the community especially since these days, BL is really popular unlike way back before. Plus Bromance is what i live for-
Well, alberu is a crown prince so he have to be manipulative if he wants to keep his position and to survive. Although i wouldn't call it a negative trait of him
Ummmm idk how to say this but like do y'all ship cale with someone in a hetero relationship??? Just curious(~￣³￣)~
