She Slept with Her Nemesis' Naughty Little Brother, and She Smelled so Good

[PS: The female protagonist has no love brain, the male protagonist is innocent and yandere, 1V1, HE] The pregnancy test showed two false positives, and the child's father was the brother of my mortal enemy. That crazy little puppy who squats in front of my house 24 hours a day with red eyes calling "sister". What's even worse is—— He took the pregnancy test report, sat on the sofa in my living room and laughed: "Sister, should the child's surname be He or Shen?" Run! I've bought my plane tickets. He said: "The He family's properties are spread all over the country, you can't escape." … It's over, it's really a crazy criticism.
