@Dead_Doll yes it is fully given on AO3(archive of our own) just search for codename anastasia (by tilly7273..) on the website, it has total 10 volumes and if you wanna start from season 2 ,then begin with volume 3...you can read it parts by parts easily in WebNovel (another web) but it only has uploaded till 5 vols! (Another spoiler- in last vol, zhenya almost killed himself for taekjoo🤭) idk how to take the link of it😭
