Midnight Tango

Kotetsu and Barnaby in a cheap tango bar.

----------

I wanted to draw some sexual tension between them, I wonder If I succeeded or not haha.
I'm sorry if the background lines looks weird, I didn't know that you actually can draw vector lines on SAI *duh* so I ended drawing this freehand.
I'm planning on upload this along with another version of the coloring to pixiv Friday night

I'm worried about the change in their relationship in future episodes, but I have faith in their inmortal love their friendship.
