Adjustment of Status - I-485

Hi guys! Today I got an update that my Interview was scheduled after almost two months. I have a concern regarding the interview about our marriage ceremony, my family only attend in our wedding (not all my family) but her family didn’t attend because we kept it secret to her family. I wonder if they ask about that is it a redflag? But right now her family knows about our wedding. We have pictures of her family together but i haven’t met her dad cause he’s not here in the US and her parents is separated and not in good terms. Our marriage is real. We’re living together in our aprtment. Her parents knows about it already that we’re living together. We have same profession and almost same age same. And we have a lot of travels picture to show, joint account, phone bills, apartment lease. And planning to travel next year on her bday. What do you guys will advice me if they us about that in our interview? Thanks
