Jungkook married yoongi, it was an arranged marriage so there wasn't anything he could have done to reject yoongi. Yoongi doesn't love jungkook, but jungkook had fallen madly in love with him only to have his heart crushed when he found out that yoongi was cheating and now it's his time to have fun. Especially with the new guy who just moved in next door, Park Jimin.
