Series in 2 arks
I like the characterization, and the setting : post-war kind of preventers but at the same time not
Heero and Duo used to be a couple of sorts during the war "lose sight" of each other and well... i'll just copy the author's summary
The Domino ArcAfter pushing Heero and the other former Gundam pilots away, Duo finds himself joining a specialist undercover Preventer unit. When a dangerous gang on L2 threatens Quatre's life, Duo has to face the past to stop a potential terrorist attack and reunite with a former ally. 1x2
I liked the writing though be aware there is some bad language all throughout and not just in the characters' speech.
Also a few unfortunate typos, would make this fic an even more enjoyable read if corrected
