Up until now, we didn't know much about Gigi, only that he is an expert at choosing wines and that he eats a lot, BUT in this episode, we learn so much more about him. I liked that instead of just focusing on Claudio and Nicoletta's romance, the anime also centers on telling us the stories of other secondary characters—like Gigi in this case, who is quite observant, which is why he is a professional wine connoisseur. He knows exactly which wine is the best for every occasion. And without anyone even telling him, he already knows Nicoletta's secret, so he's an absolute pro.
