It's one of the face graphics for the RPG making group of 2p!HetaOni
I will send you the finished expressions with coloured backgrounds after I finished all of it.
I know I should have draw the more important character first
Lol I can imagine Flavio calling 2p!Spain "Senpai" for some reasons
Somehow I wanted to draw a "Shintarou Smile" from「Lost Time Memory」expression for him xD
