This R-18 fanfiction was written by my friend and writer Jäley(葉萊) (user/84080323), who interpreted Erika in his own way and created this wonderful work showing how in an alternate timeline, Erika would interact with his original character, a German officer named Hainault.
This is a very high-quality fanfic and I am honored to share it with all of you, I hope you all like it. I did the translation yet there is a lot to improve, don't be afraid to point out the translation error.
