I don’t think Jungkook is the jealous type, so it would be kind of hard to make him jealous. Maybe in hardcore situations like calling off a meeting with Jungkook to meet with someone else. This would make him jealous and angry at the same time.
When it comes to V, it would depend on his mood actually. One time he would be jealous and another time not, so I can’t really tell in what situations
It would be easy to make Jimin jealous and I bet everyone knows that. A lot of things would make him jealous, but he would always play it off, like it wouldn’t be too serious. For example if his girlfriend had a guy friend and messaged him a lot or go on meetings withi him, he would whine all the time~~
