My Homegrown Little One Has Designs on Me

When Gu Man was eight, she was taken in. The first person she met was the poised, elegant young lady, who did not even spare her a glance. At sixteen, Tan Shuyu was a powerful and sought-after figure in the business world, rumored to have countless lovers and scandals everywhere. When a classmate said something vile about her, Gu Man, the model student, fought them like a puppy defending its owner. When she begged for comfort, looking pitiful, she was rewarded with a kiss. Later... Later, Tan Shuyu personally cast aside the delicate flower she had gone to so much trouble to raise. At twenty-two, after seeing with her own eyes the woman accept someone else's advances, Gu Man drank herself into a stupor, her eyes red with tears. When she woke, the woman who had kept her busy all night was sleeping naked in her arms. She was so frightened that her face went pale, and she was both ashamed and at a loss. The woman behind her propped herself up on one arm, amusement in her eyes. She breathed against Gu Man's ear and asked, "You stayed up so late last night. Aren't you tired?"
