If I were to describe this drama in one word it would be thought-provoking.  

This is one of those dramas that just causes you to think and I mean that in a good way.  I love how the writers went in different directions at certain points of it, and I love how there were a lot of modern ideas and thought processes woven into this one.  It made this drama feel more original.  This drama kept me hooked because I was interested in all three couples stories.  Each of their relationships were really different specifically each partner's expectations for the other and their expectations for the direction their future's should take.  I applaud the writers because it's not a typical thing for me to be interested in much other than the main couple, but they managed to keep the other couples interesting as well so that when it was their turn I didn't begrudge it but was excited instead.  Even though marriage is not really on my horizon this drama gives you a lot of food for thought about the institution of marriage and it's values and issues.  

I also felt really touched by a specific character's journey. Her desire to live a normal, typical life.  I've never desired my life to be insanely different than anyone else either and what I've always wanted is to live a life where I do the things that everyone wants to do. Sometimes you just want what's normal and that really hit home for me.

The actors do a splendid job.  Each character is played realistically even though some are exaggerated.  The exaggeration isn't anything hard to watch though, it's more just emphasis on the type of person each one is and I think the actors do a really good job of being believable and likable and more than anything, interesting.  Also, I loved Bo Mi's character!

The music is beautiful and I don't think they could have picked more fitting tracks.  The upbeat tracks make me wanna jump up and down, and the sadder more melancholic songs are very poignant to the situation.  The music definitely adds a lot to this drama.

Because This Is My First Life almost made it into my favorites list, but there was one episode or two that I really disliked and no matter how hard I try I can't quite overlook them.  I know what the point was that they were trying to make, but I would argue that they went way to far, passing the bounds of realistic and believable.

Overall: I recommend this drama! I felt refreshed by this drama and whenever that happens I think the drama deserves a lot of merit.  It's really good and I definitely think the pros outweigh the cons pretty heavily.
