Did san at least figure out that kang was a demigod?

I think he might’ve known the whole time. He probably knew when he was told what his special abilities were since they’re the exact same ones his past lover had before he died.

He also has said certain things to Lee that make it seem like he knows. He brought up how Lee was acting like he already had one foot in the grave, like he already knows he’s going to leave him.

But, I’m only on chapter 56, so maybe I’m wrong and you know more than me.
