Artist's commentary
I want to kiss
Toshiaki: "Your mouth looks like a butt..."
Homeko: "Then why do you get so close to it?"
Toshiaki: "What are you talking about? Kissing someone's butt is common sense for a British gentleman, isn't it?"
Homeko: "...Right."
...And so, they engage in this kind of silly conversation before launching into a lovey-dovey scene.
