Watched the first episode on YouTube. I'm not into subless doramas all that much, but for the most part I was even less into this one. Not enough Acchan for me. It had its cute moments and is sort of interesting, but for the most part it's a "typical" idol drama. Unlike most in that category though, this show doesn't try to be constantly humorous which is kinda refreshing. It's nice to see the show take itself as seriously as its premise allows.
If they keep getting YouTube'd, I'll watch, but my interest doesn't go much further than that.
