I was going to say she helped me realize I was in love with you, but halfway through I thought perhaps it was an awkward thing to mention to you directly, and I did not wish for our first date to be awkward, or at least I wished for it to have as little awkwardness as possible, and I think perhaps it may be a breach of etiquette to say so but I feel very nervous all of a sudden, so please try to find it in your heart to forgive any mistakes I may make. [He wants to bow, but he's still holding Daigo's hand, so he bobs his head a little instead. And catches his breath.]
