While I don't mind low-budget productions, an empty campus without any other students is just ruining the premise of the title. And what's with the over the top lipstick in the opening scene (and other), but forgetting to face-powder the one actor in the next? I don't really feel a professor who gives "love" advice. And finally why end a series with a cliffhanger? Sometimes I was reminded of Thai shows with the silly sound effects which are still annoying as hell.
This was an easy story but I guess the third person could have been spared and they should have more concentracted on character building. So few cast was a downer for me, but at least we get sensible kissing scenes which don't look forced at all.
So, this is an ok show with some length in the story telling and for me some unneeded scenes and a cliffhanger. I suppose an ex will come up in Season 2, if there is a Season 2.
