How did you get the impression of him sleeping with the concubines? I mean we literally saw his blood turn gold and him suppressing his urges using drugs...... If he was sleeping with concubines he wouldn't need to do that..... He's literally killing himself trying to be chaste..... And this isn't a short story so, what do you want all plot to be unfolded within the span of 10 or 20 chapters??
Yea , Maybe go read chap 20 again , Tei Literally says ( Oh this must be who Shuraka spent the night with yesterday ... while there's nothing unusual about a Padishah spending a night with his concubine) about the pink haired concubine... Also , i'm not talking about the story , i'm talking about the relationship, even normal people (not married couples ) would have better communication skills than these two ┑( ̄Д  ̄)┍
Didn't you read the next chapters? And this is political marriage..... They both need time to understand each other and all.... Communication takes time too.... For tei he thinks he needs to be useful while shuraka is afraid of burdening him with his love and he's scared that tei will look at him like his mother if knew what he had to do to stay alive and all..... Their relationship is starting to change, tei might need more time as he met shuraka as a child. BWAT's stories go with a natural flow, no unnecessary misunderstanding or miscommunications. They will have a beautiful relationship but it will time that's all
Tei knows ... he knew the Padishah had to kill his siblings/competition when he first Married Shuraka. Plus, he is a soldier , so he's no stranger to Off-ing ppl.
Also, i think political marriage couples usually communicate better than normal marriages since they wanna set rules and expectations. I still like the story don't get me wrong , and the art style is SO GOOD.
Shuraka is only starting to realize that tei's not like his mother. And I don't think political marriage couples will have a better communication, like the only concern is if their partnership will be boon or curse to their kingdom or something. They only have to produce heir and can live their seperate lives while staying married, that's what I've read on some comics. Like everything doesn't involve love.
Give them time, they will be communicating soon and clearing all misunderstanding and all. And I like art style too, especially the beef bottoms(≧∀≦)

This is TOO DAMN SLOW ... we need something to heppen at this point ╥﹏╥ . Shuraka isn't making any sense to Tei , he is giving the impression that he's sleeping with the concubines , and Tei thinking he's not needed is gonna be detrimental soon enough. And that Damn letter
