A: Apparently two kpop idols are dating and their fans get pressed and hysterical. They say that idols have to hide their relationships and it's deceiving fans to reveal it, even when they get caught when trying to hide it.

Your sentence already sounds pretty natural, so you could use it except change "without any of their intention" to "without intending to".

A: "Apparently, two k-pop singers are dating, and their fans get depressed and hysterical about it."

We don't have the word "idol;" you can use "singer" or "pop star."

"Pressed" means "under excessive pressure to perform."

"They say that they should hide their relationships; revealing their relationships is like deceiving them, even if they get caught unintentionally."

You don't need to use a common noun like "relationships" or "idols" twice in succession; after declaring the noun one time, you should either use pronouns like "them" or "it" going forward.

"Dating relationships" is written simply as "relationships;" the word "relationship" implies dating.

"I really don't get it—it's nobody else's business."

Use an em dash between these sentences, because it functions as one single sentence with a pause.

"It seems like they're incapable of rational thought—it's like a retarded mass-delusion."

The terms used are "rational thought" or "thinking rationally."

Use a hyphen when connecting a word with "mass." "In their minds" is implied by "delusion" so it can be omitted.

"One of my IRL friends has been depressed about this for four days and I asked her why; she told me I wouldn't get it because I haven't been a k-pop stan. It doesn't make any sense."

A: × she’s a big huge famous kpop singer
✓ she’s a big/huge famous kpop singer

no need to say big & huge in the same sentence, just one of them. also saying famous already implies that she’s big or huge, so i think you can just say “she’s a famous kpop singer” :)

A: There is a kpop boy group called EXP edition who are all from America. It seems that they have been training hard for a long period of time.

A: It should be "Do you like to listen to kpop music?"
