The peace went somewhere..
Yuri was suspicious of Lee Rang and others since the day she was attacked along with Ning in her car. She remembered Shin Wu mentioned that he was in love with Ning and wished to marry her but Ning's father had already arranged her marriage with her cousin. That day, when she was taking Ning to hospital and some people attacked them, the first thing that came inside her mind was that it was Shin Wu and other's plan to kidnap Ning. The men didn't touch Yuri nor they tried to harm her in any way but one man just injected her and put her to sleep. They attacked the driver and Ning's mother as well. When she opened her eye's she was in Lee Rang's private mansion and no one at home knew about this incident.
