Wait. I'm not getting the "Touched" sfx. What are they supposed to mean? Heavy heartbeats like "Thump Thump"? What're the original words?
I don't think "Touched" is a sfx, just a confirmation of their mental state. Though, while I understand why Yuuka's touched by Moe's words, I don't really get why Moe's touched, unless the lack of a heart means that she's a different kind of touched.
