It might just be me, but I see more of an amused, somewhat older sister type attitude in this picture. I'm not entirely sure I conveyed that correctly, so fix as needed.

Wish there was a version without the text, but alas...

Akari: does the meaning of the original text enter consideration at any point?

What do you mean? The text is what it is, but I was referring more to the way in which it is said - depending on her attitude (nice older sister, dominatrix, childhood friend, etc), the translation changes drastically. I was just guessing at the nice older sister version.

After reading the artist's description of this picture, I guess it's said in tsundere fashion. I should have realized that first, doh.
