I accidentally stumbled upon this because I was looking at updates of EXID members and found out that Hani has gone into acting. I finished it all in one day and the only complaint I have is that I wish they had given us more episodes.
I found the characters to be extremely relatable, down to their flaws. Rumi and Nana's character development was shown excellently and the pacing was just right. I loved the way they portrayed the characters' emotions through thoroughly planned scripts. I absolutely recommend watching this; it is worth your time.
