Hypnosis? or Planned?

This is over? it's kind of weird was she even in hypnosis? or it didn't worked and she pretend to be?

Perhaps she was hypnotized but her feelings for the guy still came through. Then again she seemed to remember what happened when she was last "hypnotized" when she was supposed to forget so....

Mmm, perhaps... Actually it came to mind recently but this reminds me of Saimin Appli by Mikemono Yuu. Sort of the same premise (but in a school setting) with the girl being a little domineering on a guy who's quite wimpy.
