A question about 'Under You' by E.R Gurney...

When does Beckett find out about MC and Beau? I'm on chapter 44 and last chapter was the engagement when MC found out they're related. And y'all I'M OBSESSED WITH THIS MAN (Beckett) I CANNOT HURT HIM SO PLEASE TELL ME HE FINDS OUT SOOOON.

Also sidenote: I spoiled myself and knew they were siblings (icky but not my fault, Beckett is everything) but if I hadn't known I'd be twice as pissed at Beau, like you knew I was engaged to your brother and you didn't say anything and now when I'm falling for him and everything is running smoothly you just drop this bomb on me and have the audacity to be confused as to why I'd be mad💀 YOU COULD'VE PREVENTED THIS, BE SO SERIOUS
