Ke cp, an online word, refers to expressing support for a pair of screen lovers or cp that you like or support. The original meaning of guest is "eating", but the "guest" of guest cp does not mean eating, and it has different meanings in different contexts.

In essence, knocking on cp means watching others fall in love, but some people who are not in contact and have nothing to do will also be hooked up with cp, that is, they are crazy about a pair of CP. "CP" is the abbreviation of English Coupling, indicating the matching relationship of characters.

Now there are all kinds of CPS on the internet. People who eat melons think the pink bubbles between them are good, so they will become their CP fans. However, not all CP are real couples, and some are imaginary couples. Some interactions and chats in the process of getting along made those CP fans feel very sweet and trapped in it, so later there was the saying of "cracking CP".
