Okay, I place my bets on "synth-love". I find the writing style similar to what I've already read from you. While you were working on your etol, you shared, I think, a photo or something, and what I remember from it is that I saw some type of history/retrospection. You tag a lot and this fic has lots of tags too. And something about the first sentence of this etol fic screamed your immigrant au where Taehyung turned 27. My logic is a bit erratic, but that's what I think.
