By the way, "objectification" is a big word that the internet usually associates with some lady in a sweater saying you should feel bad about a game's jiggle physics or something. But it's a bit more nuanced than that, and doesn't actually require thirst to be involved. I'm just going to say it -- Kei is heavily objectified by this plot.
Almost never actually acting, always acted upon. Even when the whole point of a story beat is Kei acting in the role of acting. Something fought over between two selfish idiots, one of whom just literally made their move while the lights were out. And the story is treating this as romantic instead of kind of horrifying.
