You can't include dramas/movies you watched previously. All dramas/movies must be watched during the challenge period.
And that about the dramas, we are already in progress of watching (since they started before challenge started?)

Also I chosen Super Easy and it feels little funny as most other users decided on Hard and Extreme and I feel so noob XD
Good few people also chosen Easy and Super Easy, so I won't feel super bad about it - I do not have so much time to watch, but wanted to participate any way :D
