Thank you for the translation (I don't suppose there's room under that umbrella for one more? Eh probably not ).
What are you even on about? She just know that they barely managed to get together and that it took several baby steps for even that to happenDid I miss something? What's with the whole "Can't tell her about sex" thing? Why is she freaking out the second the concept of her having sex with someone comes up?
If you're SO gets weirdly roundabout and prevents talking about sex up with their new girlfriend, I'd be super sus as too why. It's probably just her infantilizing her adult friend in the end but still pretty weird
