I'm not sure specifically what 'Cap deage' means. It could be a very specific term, a misspelling, or something relatively unknown. It might be a proper name, a local term in a certain area or a very niche concept.
There might be a fanfiction where two rival gamers from different manwha universes meet in a virtual tournament. Their different playstyles and abilities clash, creating a really exciting story full of twists and turns. For example, one might be a strategic mastermind while the other is more of a brute - force attacker.
Well, that's a tricky one. It could be in a particular chapter or section related to a specific event or character arc. You might have to do some thorough reading to find it.
The cap man and monkey story is an interesting one. There was this cap man who was traveling around selling his caps. He reached a place near a forest and decided to take a rest under a tree. While he was sleeping, the monkeys in the tree noticed the caps. They climbed down, grabbed the caps, and went back up the tree. When the man woke up, he was confused at first, then saw the monkeys with his caps. He was worried as those caps were his livelihood. But then he remembered that monkeys often mimic human actions. So he took off his own cap and tossed it. The monkeys, being the imitators they are, did the same with the caps they had taken, and the cap man got his caps back.
I don't have the precise release date of Jinx as a manhwa at hand. You might want to check reliable manga or manhwa databases for accurate information.
