Not entirely sure how to translate the commentary - could either be "love you" (koishicha) or a misspelling of "Koishi-chan".
It's not super common, but I do come across some commentaries that just decide to omit the ん from ちゃん. I'm not sure if it's some trend or slang, but I've been seeing it for a while. These two examples are both from the same artist, but see post #6982095 and post #6982099. In a similar vein, I sometimes see "sensei" abbreviated to "sen."
Something like this actually happened in a Darkhorse comic once. They weren't Predators, but giant alien hunters with a variety of skills and kit went after Godzilla...with predictable results.
My question is how many time they (original uploader) put in add random tags?
I just put some random letter and then choose something random. Then the "related:"random word" appeals and i click on everything on it, then "related:random word" appeals again and I click everything in it and so on.
