Love Around Episode 3 Preview (Updated)

To be honest, I don't know what to make of this preview because I don't know what is going on. There isn't much clue as to what is coming either. Only obvious thing is she-whom-I-asked-not-to-come-back is already back, after only one episode. The preview is also dreadfully short (live-shooting fatigue showing already?).

Not much in way of excitement, but oh well...
