Dude, this is old times. No one's just gonna pop outta the closet and say "Im gay bitches, deal with it". There's misogyny and prejudice, examples: Rebecca learning sword fighting, Prince Payne for being the son of a Concubine, Arth for being the son of a commoner, Sasha for not having a status and being a "pet" to the high nobles, Kanakta delegates for wanting the throne (they just want Payne, for now), Rebecca being that idiot's fiancee and having the King and Queen practically corner her into tying to knots with the prince (moving up the wedding day with no consideration to her status and wanting grandchildren already).
So of course it's gonna be hinted that they're gay, they can't just claim it. Arth had this conversation with Rebecca, she's ahead of her time, too ahead. If you can't deal with it read something modern, because this story's timeline isn't.

We can literally read their thoughts. Half of this comic is just reading their inner dialogue. There is no reason we shouldn't be able to see Rebecca realize she has romantic feelings for Sasha or at the very least say something less vague than basically "I wish I were born a man. It would be much easier to just be given what I want." *stares at Sasha longingly and then laments about how unfair it is that she can't inherit easily since she's female*

So? That's kinda the point of reading a comic? As a reader we read their thoughts because it's freaking written? It's there to give us context and depth of the characters? Old times is more romantic and all that, especially when it's just thoughts. Plus, that's such a gay thing that everyone who is gay and fell in love with someone who is straight, has done. "Wish they were gay/not straight/kinda wish I was a man/woman so they would fall for me" and then stare at them, that's gay content. Idk what to tell you, but that's pretty fucking gay and out in the open for a story in a kingdom setting. So idk why you bitching?
What's with all the goddamn dancing around the subject. We can SEE her THOUGHTS. JUST SAY IT. Why all this nuance and still relating experiences oh hardship in love to her love of Johannes back then. GAH. I just want confirmation already. Had enough of all the hinted gay coded characters within media.
