Wizard universe either canon or not: Percival and Newt are married for X years, everyone in MACUSA know about their status and are happy for them... until Newt comes to Graves' office in tears and tell him "I cheated on you" out of the blue (you can rephrase it so it's more Newtlike), and abandons his wedding ring on his husband's desk before he flees MACUSA.

Heartbreaking moment for both Percival and Newt for the first is very confused and shocked but does not believe a single of Newt's words, and for the second was tricked into believing that "rape equals consensual relationship, so cheating" (you can use anything to justify the rape).

Bonus:
-One of Percival's co-workers is the mob (for whatever reason, I expect jealousy?).
-The others begin to have doubts about Newt and pressure Percival to break up for good (but the latter is stubborn and believes in Newt).
-Goldsteins sisters + Jacob are Newt's supporters.
-Theseus comes to MACUSA to help Percival in discovering the mob.

I would really like this fanfiction to be as long as possible considering there'll be kind of an investigation scene and of course really well written! I know I am demanding... sorry about that...
