dubious age gap tbh but it turns out fine. was super cautious reading this and almost abandoned it a few times. but in general I think it does explore the question of “what if fated mates are separated by age” and the answer to that is to build a relationship but only let them get together when they’re adults and that’s not a bad answer

would not reread solely because this put me through an emotional meat grinder - very discriminatory omegaverse society, CW lots of rape culture things, SA pictured several times - i feel like a lot of these omegaverse fics reflect real life gender dynamics and highlights discrimination which is nice - unique a/b/o in that they choose love over their “fated pairs”— which i really love. love is more than biology ;)
