Pretended
The headlines in the news the next went like this: "Mo Yifan's house catches fire, did the curse from Chen Waan strike again?"
Well, it was indeed Chen Waan's doing but what else did they have?
According to their plan, auntie Zhou had managed to light a fire in the kitchen and produce smoke by burning a few paper towels and kitchen dusters. That was enough to ring the fire alarm and call the firefighters.
They had to take the action immediately because there was supposed to be no time lag between the fire and the people running out of the event venue. And it had to be big enough to call a few authorities.
Chen Waan had already vacated the house so that only one person was mentioned in the report. Auntie Zhou was successfully pulled out of the house on fire. Wang Zenghao went to Mo Yifan's house and praised Chen Waan's presence of mind.
