Or videos or vlogger, just anything 'real' and no acting nor """no acting"""" ????

Preferred: something short, so I could watch something daily w/o sacrificing time for school works.

But feel free to recommend something that's not short, I hope you'll mention it tho.

Thank you ????

These are long but never fail to make me laugh: Running Man, Infinite Challenge, 2 Days 1 Night. One episode a day would be satisfying; however, each episode is quite long. 

We Got Married could be short if you watch one couple at a time. http://kshowdaily.net/ subs it by couple, which makes each episode about 25 minutes long. 
I agree with JOJO but if you want like 10-15 minutes of vlogs you can watch

also almost all kpop groups have their own shows, examples: MTV V Diary (vixx), This is INFINITE (obviously infinite), Fruitful Trip (JYJ), etc.
I'd recommend you to watch the K variety game show Running Man. Also the J-game show called Takeshi's castle :) There are some episodes on You-tube and they are usually short....https://www.youtube.com/watch?v=0DS8JFcjNrE
