You can see she’s wearing the boy london sweater and coat as their “couple clothes”.
Her name is Park Sewon and she’s a year older than Jungkook (that NOONA killer), apparently she’s actually pretty famous amongst netizens for being a “PRETTY ordinary citizen” (일훈녀), basically like an uljjang status i guess. The comments below r basically saying they’re shocked at the news but they wish them the best and happiness because it’s their lives not the fans. Some speculate that they’ve broken up and some say they’re still together.
The TWEETS are basically some fans heckling at her about it and she’s just telling them it’s none of their business.
Anyways, in my opinion that is Jungkookie next to the girl 100%, i mean look at that eye, its his eye!! and those bulky carpenter hands of his. So I do believe that they were/are still dating. She’s apparently following BTS on twitter still which leads me to believe…….. that they’re still together… but that’s just my guess. Jungkookie is my bias so obviously I was shocked/DEVASTATED when I first heard LOL but I mean it’s to be expected!! I wouldn’t expect less actually, he’s a hot famous celeb and she’s pretty to match! but not gonna lie i was SOOOOO SADDDDDDDDD the day i found out haha lol even though i could practically be his ajumma sigh……
