"Just by having Yamada with me I can go from ordinary to super-human."
I love this line. They really build each other up, as a couple they're greater than the sum of its parts.
Phrasing, Anna. She made everyone else in that elevator super uncomfortable without context. Kyou actually blurted out the context so they won't be misunderstood.
I think Anna is on the right track with how she views life experiences. For her, it's different every time. With the right perspective, there can be so many firsts to enjoy: "It's our first time together here." "It's our first time this month." "It's our first time this week." "It's our first time today." and that can make it so much more special than simply thinking "I've been here a hundred times".
If Niko was behind the condom prank, maybe they should just leave her be with Momo and friends... also don't tell me that's Kana-nee lying face down and plastered on the floor.
