They meet by chance. Taehyung was delivering a delivery late at night when he was attacked and robbed. Jungkook was driving by in his luxury Audi. The thief tried to escape at the sight of Jungkook, but Jungkook's men tracked him down and killed him. Jungkook hates liars and thieves.

Since then, Jungkook has been visiting Taehyung. Taehyung is approachable. They're both drawn to each other, but both remain silent. Jungkook is afraid to admit his feelings, because it's unmanly, but he still breaks down and goes to Taehyung. And Taehyung remains silent because he sees Jungkook's inconsistencies and doesn't push, even though he admits to himself that he's in love.
