Gucci are happy with IU and Kai, they don't need V. Has he even shown any interest in Gucci in the last few years?
I get why some of his fans might feel triggered, but Celine have just been made very well aware of the value he could bring to their brand, and they showed him a good time in Paris. If Celine is his preference then it's going to happen. Once we get past the t-shirts, I don't think Celine's current aesthetic suits him. Hedi designs for tall and super skinny. Lisa carries it off, V not so much. But what BTS members want, BTS members get, right?
