After My Girlfriend Got Pregnant, I Came to Her House and Slapped Her in the Face.

I've been in love with my good brother's sister for less than a year. I was thinking about how to confess to my brother that I was secretly with his sister. But he said that his sister was suddenly pregnant and was getting engaged, and he invited me to witness it. I have been using contraception with her for so long, whose child is this? At the dinner table, my girlfriend and her boyfriend were cuddling with each other, so unhappy. I smiled, "Zhou Ya, are you really sure who the father is?"
