I watched a few episodes of "White Color" on Hulu.

It was interesting, so I'll continue to watch it.

However, I noticed that the drama will have the plug pulled in season 6.

I think American dramas are really interesting, but I also think they are too long.

Please don't extend story just because it became a popular, please don't become strange final episode.

I don't know what will happen in future episodes of "White Color", I desperately think so.
