Why do the emojis look as if they were made for this content >u<
They weren't. I was going to source some random anime pictures online but those emojis came at a good timing and they're original > copy paste sauce.
On a more related note, somehow I follow the same format without knowing about the format? >u<
You have learned the culture. It's more along the lines of experience doing its work at the back of your head. You know something is right or wrong just by looking because you've seen better and know worse. And the best reviews posted elsewhere follow the same format but have different variations.
