I am so sad to say that it was a disappointment. I have watched this because of Yujin, I am so happy that she comeback to acting, her role was cute but to be honest not really challenging, if she wants to act more she really needs harder roles - but I do believe it is hard to match with being in group.
Acting of boys - no, sorry, there were too many momenst were they looked stiff, they acting felt forced - and I know it is Xion's debut so he needs to act more to get better.
Too little music for music drama - and I was hyped up after first scene, so it is a pity. Yujin's character fate was predictable. And advertisements/product placement were annoying in this one.
