Yeah, it's great! I think it reminds me of Kyari Pamyu Pamyu a bit (although it's been a while since I've watched one of her MVs) - definitely the vocals but maybe the look as well? It's obviously got a retro thing going on with the car and the corded phone. The colour palette makes me think of the Barbie movie. Maybe this is quintessential city pop? (I'm terrible at categorizing music and style )
I'm a big fan of synthwave songs but I don't love Hoshikuzu no Escape. Imo her voice isn't strong enough to completely carry it. I feel like Owaranai Insomnia suits her voice a lot better, so I prefer it more just based off my first listen. (I think it also has the better video of the 2.)
