Optimist, Pessimist, Realist - Jimin x Taehyung x Jungkook x Reader

WARNING: Some mature language or themes may be offensive

-and now the desc.-

The three youngest are always the troublemakers, but when she comes around they practically invent a new way of trouble. All three are different, all three are competing for the same girl. Will their simultaneous love ruin their friendship, and how does the girl feel?

"Usually stories like this would be a love triangle but we're four people so..."
"Then I guess its a square."
"No third wheeling for the lucky guy."
"We're a full car."
"Beep beep, bitch."

When Jin suggests that Jungkook, Jimin, and Taehyung should go on a nature trip (to "get along better"), they all want to take Jisu, the only person who can stop their conflicts. While on this trip, they get lost in a cave, at first only a joke to go in. And only there does shit go down.

"Okay guys, what happens in the cave stays in the cave."
