If I can get Jin Lühui to spoil me, why would I need your measly few coins?” Her friend warned her, “It's not appropriate to live at his place when you're not married.” She packed her bag. “He gives me money!” A suitor asked, “He only keeps you as a pet. Why not break up with him and be with me?” She showed him a transfer receipt. “He gives me money!” - Jin Lühui was now getting a million times over what he hadn't been able to have before. Wen Suizhi had changed. He skipped class to pick her up from the village, and she transferred to his school so they could walk to class together. When he was hungry, she cooked for him. When he was thirsty, she brought him water. When he was unhappy, she soothed him, hugged him, and kissed him. She even climbed into his bed in the middle of the night. He swore that if she ever ran away again, he'd break... his own legs, so she would have to take care of him. Everyone said, “She only loves your money, not you.” Love-struck, he scoffed. “Ha!
