Jungkook could still remember seeing her leaving the concert that night. It was too painful for him and he started to cry in the middle of “Whalien 52”. It was not right that fans started to cry seeing his pain and members needed to hug him after. It's definitely a sad ending for him.

And he never see her ever since.

It was painful for him. Too painful. And yet, what he did? He play with more girls. He made promises to Erin that she would be the last girl he hurt, and yet, he added more right after her. He barhopped, he drink and of course, hit on more girls. It's Just Jungkook and his first heartbreak and how he will pay the debt that he made during those dark times he had.
