aw.....they flirting at the few last pages is so cute. but I wonder, since Ayu's status have been "upgraded" from "live in-helper" to "live in-girlfriend", can this be used by Ayu to get more control of Hikari? considering that Hikari keep slipping to her procrastination tendency. I hope Ayu realized about this, since this benefited her too, as more earlier Hikari's job finished, more time can be used for both of them to be more intimated and doing whatever they want to without being disturbed by Miya-san
