The music video makes it seem like Jungkook is the love interest, the person Charlie Puth is hallucinating about.
And he called Jungkook "a very attractive human" and "handsome guy" out of nowhere in the interviews. Mind you, Charlie is gay!
Honestly, I felt he was a bit more excited for this collab than he's supposed to be. Kept on praising Jungkook and mentioned things about JK that only fans would know or care about.
But is he smitten by Jungkook or his popularity? I heard he's a clout chaser, so I'm thinking I might be wrong.
