[Oh... crap. She hadn't realized how confusing this could end up, especially with both of them being shinki! She'd better just clear this up directly, huh?]

Ah, sorry! I thought you looked familiar, but I didn't recognize you at first. We both looked really different last time...

[Yeah. That small girl Naoto had met, who was so starry-eyed about ~idols~, is now by all appearances very grown up and wearing cute costumes to advertise a local sweets shop. Despite her figure though, she's really not quite an adult (as far as she knows). Naoto looks younger, perhaps, but they might be closer in age, or at least general maturity, than either of them would assume.]
