You and Shu were at a very elegant party in France. He was there as an invited guest and you were his companion. Since you had no idea what other people were saying or what was written on the labels, you had to stay close to Shu so he can translate some stuff for you. At some point Shu asked you to get something to drink. You didn't know if it was appropriate to check something by smell so you had no way to know if you brought him wine.
