Im pretty sure that no matter our choices (if ocean really manages to finish both avn's haha) there will be a more or less canon Wiab ending for SG.NTR aside, I always got the impression the original WIAB had an option for William Zane to ditch/break up with Miru and pursue other LI(s).
SG blows that option being canon out of the water. Ayua Zane in SG - (a) who has Katie Zane (William's sister) as an auntie, (b) is of Asian descent, (c) and is a fighter who knows Miru's secret family fighting style - points to William and Miru reconciling any drama and likely marrying.
The only outlier scenarios I can think of where William/Miru don't marry are:
(a) Katie Zane is an auntie and Ayua carries the Zane family name through either adoption from an estranged/deceased Miru or see (b) below.
(b) Ayua is of Asian descent and although Miru is the likeliest mother, Ocean revives an original WIAB plot where Miru's Japanese crime family discover Miru's location, travels from Japan to Wollust to confront her, and William gets it on with some sister of Miru (!!??).
(c) Ayua knows and practices Miru's secret family fighting style and the only scenarios where Miru didn't teach her are either Miru teaching Leia and William enough of the secret style for the Zane family to steal it or see (b) above.![]()
And i dont think Ocean will involve NTR and even less NTR-Pregnancy in the canon ending as it would just upset too many people and would make the LI in case unlikeable for a huge amount of players.
And considering the way Wiab is set up so far i feel like everything leads towards William and Miru having an open relationship and Miru starts to like the idea of Willy putting babys in a lot of women at some point lol.
Miru and Willy just arrived and Miru is shown to be bonding A LOT with the other girls already, sometimes even siding with them against willy (which a lot of insecure bitch-.. uhm .. players already cry about) which is clearly to a) win them over to like Miru but b) Miru getting really close to them too.
I wouldnt be suprised if she discovers a cuckquean fetish or something adjacent to it, i cant see this happening (willy impregnating the whole town lol) without her support and encouragement.
I think as long shes sure that willy loves her and screws her often enough, Miru is up for a lot of stuff in the long run lol
