The visitor is Su Qingyu's distant cousin, Cheng Ruijin. Cheng Ruijin's mother is her aunt, and the two of them have been living at the Su residence.,She had been married to Shen Zhao for three years without consummating the marriage. Shen Zhao's reason was that "that side" didn't work. She bore the pressure from the Shen family alone and secretly studied pharmacology. Since Shen Zhao didn't even have a concubine, she didn't suspect anything and instead cared for him everywhere, fearing he would feel inferior and depressed.,For Cheng Ruijin, her family background was like a thorn embedded in her heart. Fortunately, three years of forbearance had not been in vain.。
