some novel readers wanna spoil the ending for me?

I'm not an actual novel reader, I just looked at the last chapter to spoil myself lol but they end up having children together. I think multiple, but I'm not entirely sure. Seems like they have a happy life. The son at the very least is content, he makes a comment about how at first he was in control of his dad, but now it feels like his dad controls him (because of how whipped he is)

what rhe flipppp

i remember only seeing other spoilers that mr park got twins so...
