Before the accident, Selina, as a member of —SHE, the most popular women's group at that time, was not at the same level as the fledgling Ham. The two met because of filming. After the explosion, although they were not worried about their lives, both of them were burned to varying degrees. Afterwards, Ham's public relations team trumpeted that Ham spared no effort to rescue Selena regardless of his own safety and helped Selena put out the fire, thus suffering more serious burns.
However, after this incident came out, Selina did not mention Ham's case in many talk shows. It can be seen that Selina thought that ham didn't save her, and Ren Dad said "grateful" many times without mentioning ham. Selina must be very dissatisfied with Ham's handling afterwards, which is false. He thinks that Ham put himself on the moral high ground, won the sympathy of the public and climbed up on his own.
We don't know what the truth is, but judging from Ham's attitude and practice in this matter, Selena has enough reason to hate him. After the accident, they all made hype, but the content of their hype was quite different. The woman emphasizes "seeking justice" and "rebirth", while the man focuses on "saving the beauty by heroes" and "keeping a low profile". Their positions can be said to be completely opposite. Of course, both of them are victims of this incident, and more are the interests of the team behind them.
