He knows.

      He knows what Yoongi does, where he goes every other weekend.

      It's not like he's naïve (contrary to popular belief). He knows Yoongi goes to clubs and gets drunk. He knows Yoongi picks up young, doe-eyed boys who are none the wiser.

      Yoongi loves him, he does. He just needs more. He doesn't feel satisfied with Jimin and he isn't sure why that is.

      He says that "if he could, he would stop," but they both know that's a lie through and through.

      Yoongi knows what he does. He knows it pains Jimin, knows how it makes him feel (or rather, how it makes him feel nothing, empty inside).

      It's just that it's become a habit and he can't stop now.
