I would rate this 3/5 because the ending was really disappointing. I really liked it so much at the beginning but I lost hope seeing the main character looking weaker and weaker each episode. I do like the female lead character she's really motivated though she's made mistakes in the past she's eager to get better.
I just thought it could have had a better ending which I think the story deserves. Just give it a go you might like more than I did! Sorry I just didn't really like how it ended!
PS. Season 2 won't hurt - this series deserves more and over-all actors were great!
