Come for the fun credit sequence and stay for, well, some of the secondary characters.

This drama might be more enjoyable as an all-at-once watch rather than a live-watch because you lucky Future Beanies will know that you'll be getting a show that is more like a series of vignettes about "being yourself" than it is about any one given coherent story. It certainly isn't about what happens when a man--a newscaster, even--mysteriously and magically becomes unable to say anything but the truth.

I bet that if you fall in love with any one given character, a light-hearted watch of this drama would be worth your time. But I wouldn't expect you'll end up immersed--it's just not that kind of thing.

If that is alright with you, I would appreciate it if you spare a few minutes to read my thoughts on the drama. It might have been all over the place but it had its fun parts.
