Blend S is a show which no one will really get together. Blend S is mostly comedy.
The cafe is where you will play a character, which is like the opposite of what they are.
Not all of the show is in the cafe, they do go out on a trip together, like twice.
The op is pretty good, I always no to the trap (lol). You can watch a few episodes a day, nothing too serious, just a soothing anime where you can get some laughs.
