The commentary seems to ask something to the effect of, "Which teacher do you prefer?" If we're going with a "hot teacher" angle, I like the one on the left the best, and the one with glasses is a close second. :-)
It would be interesting if a girl from a vintage family is teaching classics, flower arrangement and the like to base on the kimono... and the one wearing the aran sweater looks like she'd fit right in on home economics~
