New Journey to the West, all the seasons are great but 3 and 4 are especially hilarious!
Youth Over Flower: WINNER is really heartwarming and fun, even if you don't like the group you'd enjoy it. It's only 4 episodes and I would highly recommend it!
Wizard of Nowhere is a nice travel show and the cast is fun.
Hyori's Homestay is an interesting show, Hyori and her husband are fun to watch, IU is great, and the guests who stay at their house are cool. Also, so many cute pets!!
Half-Moon Friends is a show where the group WINNER start a nursery and have to take care of 10 kids around the ages of 2-10. It's so cute seeing the guys interacting with kids and the challenges they go through.
