there's some kind of bottom line in terms of appearance this person won't accept, not really sure what would be the ideal phrasing because of my poor Chinese + no context go by Presumably if it's regarding a person then no matter how nice or capable they are it doesn't matter if they're too ugly if it's some kind of object, like idk a Mecha robot then even if the Mecha would be more powerful it's not OK unless it also looks cool enough Literal dictionary tl would be: Absolutely can not give up on the bottom line in aesthetics p.s. why are there spaces in the raws? I doubt there should be any 绝不能放弃审美[space]底线[space]......!
I'm assuming the context is that mc is starting to think that something they initially wouldn't think is beautiful is getting more beautiful in their eyes "I must never think that this is beautiful!"
