If I had to write the synopsis for this show I would write this:
This story is about two girlfriends who are strong independent women, balancing their parents’ cultural norms with their own need to live life on their own terms; pursuing their own dreams. It is about how they find love customized to them and supporting each other along the way.

We see familiar themes as each “sister” finds her own unique (“Customized Love”) love story:
-Compromise between traditional parental values and modern notions for marriage
-Female empowerment for career and dreams within the context of relationships and marriage
These are not new themes but worth retelling - and the acting and chemistry in this drama makes it worthwhile to sit through and embrace the message again.

I found myself enjoying the relationship between the leads in this show because the characters are written to have mutual respect. Both main couples are honest and open with their feelings and mature in their handling of falling in love. When they become a bit childish there is a best friend to pull them back from the edge.

If all you want is the romance, the tantalizing interactions between the main couple should satisfy this need in spades! I found myself thinking many times, “I wonder if they captured that movement while they were taking a break from filming and decided to use it?”. Their interactions were very organic and natural. I felt the same with the friendship between the female leads. They have great chemistry as well – I wanted a best friend like this.
This was the best part of the show for me. Because I enjoyed the romance and feeling you get from this type of on-screen chemistry, I was able to finish the drama.

However, it was not without the liberal use of the fast forwarding button - the show definitely could have been done in less episodes. I also found there were characters showing up conveniently to move the story (as with all dramas) but in this case it is awkwardly done (abandoned storylines) and this distracts from the quality of the show.
There were also a few points where the script failed the actors (this tells how well they did their job because they were able to shine regardless).

…but the pretty fashion, gorgeous sets and SIZZLING CHEMISTRY makes it worth sticking through to the end.

Side note: There are messages in the drama that resonated with me:
First half: The fashion industry fighting to protect original design in a world market that is overrun with knock-offs due to mass consumption.
Second half: Security of our online data has become an important aspect of business and has the potential to destroy firms.
Throughout: Run your life/business with integrity and be willing to compromise and forgive in love/life.

Finally: did I mention the chemistry, easy banter and skinship of the two main leads? :)
