The central themes of this series are friends and family, and what exactly makes someone family. In many cultures, biological parents--no matter what--are given unlimited respect, even when love isn't present. As it was stated in "Boyz and the Hood:" Any fool can make a baby, but only a real person can be a parent. Of course, I'm paraphrasing, but that is the gist, and there is a lot of truth here.

There are still those that might feel that adoptive parents can never be real parents. This is a lie...as much of a lie as saying that a biological parent is the only requirement needed. Mi-Jo's mother and Seon-Woo's father are despicable people who can never call themselves a "mother" or a "father."

Frankly, there are a lot of people who shouldn't be parents; those who are incapable of accepting the responsibility to love and be there for their kids. We see several examples of this throughout this series.

The series centers around three women, all of whom are thirty-nine, and have been best friends since high school. We quickly see just how involved they are in each other's lives, how much they love and care for each other. The strength of that bond is put to the ultimate test when one of them finds out that she is terminally ill.

While this may seem like a melodramatic plot, it really isn't. I am constantly amazed by Korean series and the actors and actresses who are able to simply "be real" in these types of situations. It's not too much and it's not too light. Perhaps that is why they are able to make the audience feel what they are feeling so acutely.

The three leads have undeniable chemistry as three besties! Chan-Young (Jeon Mi Do from "Hospital Playlist), Mi-Jo (Son Ye Jin from "Crash Landing On You" and Joo-Hee (Kim Ji Hyun). There is laughter, teasing and light bickering, joy and tender moments when these three are in a scene together.

What impresses me the most about this series is how family and friends are always there for each other through thick and thin, and it feels absolutely genuine, and this is tested when the time on this Earth is going to be cut short for one of them. We see how this affects each person who's intimately involved.

There's no denying the acting strength of the entire cast, but Joo-Hee (Kim Ji Hyun) was my favorite. She's the somewhat shy and slightly aloof member of the trio. She gives us grace through soft, warm smiles, and it would be a mistake to perceive her as being weak, when she, in fact, has a quiet strength. The scene at the department store with a very rude customer is a testament to this.

The other performance that impressed me was that ofJin-Seok (Lee Moo Saeng) as Cha-Young's love interest. When his voice cracks and goes high-pitch with raw emotion in several exchanges with Cha-Young, made me choke up a few times.

I also loved how these characters never gave in to abuse or intolerance. Mi-Jo's confrontation was a thing of beauty; nearly as impressive as Seon-Woo's showdown with his father.

The last episode will be a tough one to get through. Even when you know what's about to happen. That's the hallmark of great writing and storytelling; when you know what's coming, and it gets you anyway.

I dare anyone to get through the brunch scene with a dry eye, or the video message that Cha-Young leaves for Mi-Jo. Both were absolute scenes of beauty.

There aren't enough shows out there that truly showcase the power of family and friends; that demonstrate that love and being there for each other are the pillars of true relationships. If you don't already have such people in your life, this show may make you wish that you had. It will also challenge you not to take your loved ones for granted. We never know how much time we have with them. Spend it with love and devotion. In the end, Cha-Young is correct: quality is always more important than quantity!
