I watched Blue Birthday because of Yeri. As a Reveluv and a Yeri bias, I get so happy whenever I see her acting. Ever since I started watching Blue Birthday, I've been so happy, like from the very first episode. All the scenes are beautiful, there's not a single boring one, and I cried so much in some scenes. I hope this K-drama series gets more recognition. Since I watched it, I told myself that this is now my favorite K-drama, starting now.
