I felt like I was all of the characters mom. Seriously. I saw all of them grew up and had character development. I cry at kdramas but this one is the only series that made me cry while washing dishes thinking about what will happen in episode 20 and my mom was a witness lol. The cast were amazing. They portrayed their characters so well making me believe that it was actually their real lives. The story was astounding on how their lives were connected and every character were given almost equal exposure that probably was the reason the viewers got attached to this series so much. The twist on my OTP though was so unexpected that it really made me cry a bucket.
