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.

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

Xiao Shu: As long as it's in the right direction, you'll definitely find your happiness again!

Zhou Zhen: She's... my ex-girlfriend.

Ok, we have a little more - Zhou Zhen and Xiao Shu go to a baseball match, presumably to cheer and support each other through their break-up slumps, and somehow end up in more skinship-inducing situations. Still not sure what Miss C's deal is.

I haven't really heard from anyone else who's watching the show - what are your thoughts?
