Fans claim that it was a homage to olivia rodrigo but considering olivia demanded that mv to be removed its obvious she didn't liked it.
And can't even blame olivia, yena was just trying to gain clout using that click-baity title and hashtag and profit off using Olivia's well established name and imagery, this must be the biggest reason why olivia retaliated using copyright instead of appreciating yena's "homage" to her and ignoring the copyright issue. This attempt of her made her look more like shameless attention seeker than a fan, although her attention seeking attempt was successful and she did managed to get Olivia's attention, congrats i guess.
She even used Olivia's imagery in album and photo cards etc too, yena needs to get sued hard
