They practically are. They sleep together and are raising two kids. That's damn good for China.
And they're not related.
In the writer's defense, A is weirded out AF by his brother's advances. That relationship is not treated as normal within the story.
Then why are they still trying to make the brother look so calm yet creepy. As if he's not the villain or he's not doing anything wrong
The fact we think he's creepy and weird, and A is also put off should be enough. They'll likely end up together, but before a lot of BS nonsense. I'm desensitized to BL story lines at this point.
FRR but I'd like it better if they're officially married. Manhua's stories are badly expressed despite their concept, this one was going fine until the kinda-incest but whatever
It's China, we're lucky to have a family unit.
Main couple is better. MAKE THEM GET MARRIED!!!
