I'm bringing up this topic because there are so many options, seeing how everybody knows each other. Here's the cast list that I got from asianwiki:

Lee Min-Ho	Park Shin-Hye	Kim Woo-Bin	Kang Min-Hyuk	Choi Jin-Hyuk
Kim Tan	Cha Eun-Sang	Choi Young-Do	Yoon Chan-Young	Kim Won

Kang Ha-Neul	Krystal	Kim Ji-Won	Park Hyung-Sik	Jeon Soo-Jin
Lee Hyo-Shin	Lee Bo-Na	Rachel Yoo	Jo Myung-Soo	Kang Ye-Sol

Lim Ju-Eun	Kim Sung-Ryoung
Jeon Hyun-Joo	Han Ki-Ae

 Lee Minho and Park Shinhye are probably  bound to happen but after they go through a lot of heartbreak, deception, lies and tears. Young Do is going to start falling for her too most likely in the next episode (ep. 7) so he'll just add himself to the love triangle that already exists between rachel-tan-eunsang.

Other than that, there's Lee Bona and Chanyoung. Well obviously, I want them to stay together. They look really comfortable together on-screen and in real life. (Krystal seems to be comfortable around any guy she is associated with. I even loved her with her partner in Kiss & Cry). 

If all my ships mentioned above do work out, then maybe Rachel and Youngdo will end up together. If not, there's Yesol who seems to be interested in him as in a conversation she was having with Krystal's character, she called Youngdo hotter than Kim Tan. That leaves Myungsoo and Hyoshin. I think Hyoshin will start to date Hyunjoo and the older brother, Kim Won, who obvioulsy likes her will be conflicted. Perhaps it will come to his realization that being in charge of the company and making sure that Tan doesn't get his hands on it, is getting too much in the way of his personal life/love life.

We will see what happens. I can't wait for episode 7 which comes out next Wednesday!
