Oh there are so many to choose from, but the सेकंड season hit on this couple the hardest! I like when the butlers fought like school girls over Ciel (ex. Sebastian Throwing the cake batter in Claude's face as if to say, Dont look he mine!) and there are so many moments in the मांगा as well! Who ever says these two are not meant to be can deal with me!
I loved it when Ciel was trying to get a picture of Sebastian and Finny threw the statue up in the air to land on चोटी, शीर्ष of Ciel, and Sebastian saved him from it. They looked like they were supposed to किस right there and then Lau set off fireworks, and even he thinks they look good! And I quote "You guys make a charming picure" xD It was hilarious, adorable, and one of those moments in याओइ ऐनीमे and मांगा when you're all like "COME ON! किस HIM!"
