Thanks! This time I Googled "石井香織 着替える眼鏡女子" and found several comments by people who think it's Kaori or at least looks like Kaori. It looks A LOT like Kaori...but the moles seem off. On the other hand, Kaori has a lot of moles, and she may be hiding some of them here with makeup. Also, the voice sounds different to me, but, again, her "idol" voice was probably an octave higher than her ordinary voice. This series uses supposedly "ordinary girls" (素人), and this girl seems very natural and unpolished. Is it Kaori? It could be, but I'm not 100% convinced. She's cute though!
