I think it was his sweat....
LOL XD
I'm assuming this is sarcasm as I'm looking at his glassy eyeball not his skin. Sweat is salty so his eyes wouldn't be open in a relaxed manner if they were getting soaked in sweat.
That is to say, tears are salty also obviously, but the saline level is different. Irregardless, he's not sweating in his eyeballs.
Ahhh I see... not trying to be sarcastic or anything, I just didn't notice his eyes
(=・ω・=)
No worries! ^-^
As an artist, I'm always looking for little nuances in illustrative story-telling that act as a window to broader understanding of a scene and/or emotions, and I'm wondering if I'm the only one that noticed Kang tearing up on page 6?
