Why kidnap the son in law who isn't even related by blood. There would have been plenty of other better picks.
Zhang Xi Yong's mistress was Ye ZiXi (also an heiress of Ye Corp and Ye Qiao's cousin). The criminal was madly in love with Ye Zi Xi and angry at Zhang Xi Yong for taking away the love of his life and putting her in the mistress position.
