CKE18 - Graduation Tease

I don't easily get embarrassed but Harumi made a comment during this set that made my face turn a little red. She said this set felt like high school graduation photos. At first I thought that was a compliment, but then I started thinking about the perverted old men who usually shoot those pictures. Was it an innocent remark or was she calling me out?! Sometimes Japanese girls are too clever for my own good!
