The one who paid the reporter to spread the pictures he had gotten when he stalked He Gui and paid for the hot topic to a platform in order to reach the top trend list was Manager Bai.
The reporter told her that He Gui was seen escorting an actress into a restaurant and the other reporters also saw all of this. However, Manager Bai didn't inquire further about who the actress that was recognized and quickly had the reporter she hired to post it in a marketing account. She would then take care of the money to pay the platform to boost the rankings of the topic in the hot trend list.
This would result in He Gui being sprayed with dirty water with a dating scandal with an actress. People will then accuse him of being a hypocrite for tossing Tang Jian and trying to get back at her by dating an actress while being engaged to another Miss Yin.
