"Yes."
Claus didn't hesitate to answer without even needing a second thought about the wonderful question that would lead to changing his life forever.
Awesome! I finally got my Baby! It's the start of my amazing love life!
As for the meaning of being asked to be a wife, it doesn't matter to Claus as long as he could get together with the person that moved his heart. Besides, as the wife, he would be extremely thoughtful and perform all the hard work when it comes to their bed matters.
… cough… calm down… don't be excited… don't scare the love of your life… or you will end up crying miserably...
After all, Claus also understood that his newfound lover doesn't really have any deeper feelings towards him. The word 'responsibility' was spoken before Snow asked him to be his wife and that Snow was only forced to speak such words after checking the information on the internet.
