Du Yujiao has good reasons to treat Zhu Bufan so well. Over the years that Du Yujiao has been married to Zhan Yucheng, she gave birth to two daughters for him, Zhan Feiyu and Zhan Feihuang, but never managed to have a son.
Zhan Feilong was from Zhan Yucheng's previous marriage; Zhan Yucheng's ex-wife passed away many years ago. After Du Yujiao joined the family, she became Zhan Feilong's step-mother. Although she never abused Zhan Feilong, their relationship had always been lukewarm.
Du Yujiao doted on her two daughters undeniably.
However, Zhan Yucheng held his son Zhan Feilong in very high regard. He greatly valued Zhan Feilong, who was quickly appointed to a senior position in the company right after graduating from university—his rise up the ranks was meteoric.
