Lmao she is definitely gonna get pregnant. That’s why it’s within a 300 day time frame.
I’m also pretty sure the other guy likes her because that’s how it’ll typically be. Hopefully no NTR but there’s obviously gonna be that guy with non-reciprocated feelings trying to make a move. This part though. Either moves that are fine, or like what some authors do, overbearing advances that’s likely harassment, or even sexual harassment. I hope not.
