Jimin(idol)

Park Jimin is a member of BTS, everyone knows that. Fans ship him with all the members, especially Jungkook. At first it was just fanservice, which Jimin agreed to. However, as time went on, fans started taking it too seriously.
There were a lot of jealous comments under videos that were 'Jikook' themed. Of course, after a while, Jimin got tired with it too. Secretly, he got tired with having to hang out with Jungkook all the time. He got tired of having to touch him all the time, to make it seem like there was more than just friendship between them.
Jimin knew that the Army loved him for confidently embracing his softer, and more feminine side in front of the cameras. However, that didn't mean he had to spend all his time with Jungkook. However, there was you, one of his best friends, with whom he sometimes slipped a little extra into their friendship despite everything.
You were a handsome and mascular men too, by the way, and Jimin didn't mind it at all. After a while, Jimin ignored the fanservice and jungkook and started making up for lost time, because he had to spend all his free time with jungkook before, so he neglected you and everything else.
He even hung out with you in front of cameras and even took you to events he was scheduled to attend. You met the members, but you and Jungkook didn't really like each other from the start. It was kind of a mutual thing.

Jungkook jealous when he sees jimin and you they behaved intimately in front of the cameras, fans and everyone, because during the time they spent together, he developed feelings for Jimin, and it bothers him that Jimin spends less and less time with him and ignores him.
