Very well written!

Oh my gosh, this was so wonderful to read. I love how Russia here keeps blaming the wine, how he's not so sure of himself either even when uninhibited by the alcohol. It was a short little oneshot, without much dialogue, but all the body language does the speaking for how he feels in this scene (the fond glances, the attention Russia pays to Yao, his panicked moment of trying to play it cool?! agh too sweet)
And then Yao's "I'm glad you're here" - my RoChu heart exploded.
Anyways, thanks so much for sharing! I really enjoyed this oneshot :D

Oooh I like
