I appreciate you reaching out, but I notice the text you've provided is actually in Chinese (Simplified), not Japanese. The text reads: "A Story About the Lover of a Woman Who Engaged in Egg-Dumping" (Where "托卵" refers to the practice of leaving one's child with another person to raise, or metaphorically, infidelity/cuckoldry.) If you have Japanese text you'd like translated, please feel free to share it.

This is a story about the lover of a woman who engaged in "cuckoo-birding" (having another man raise a child that isn't his). The reason why it was discovered was because the lover bragged about it at his workplace. Whether the man's story was true or false is unclear... ※Warning: Contains cruel descriptions (this is just precautionary).
