Jiang Mei, the heroine in the play, was born ugly. Because she is not only ugly but also fat, she decided to lose weight. However, even if she succeeds in losing weight, it won't change her appearance.
It is because of her appearance that Jiang Meilai has been bullied at school. She has no friends, and her classmates laugh at her when they see her. Even if she has a boy she likes, she wants to summon up the courage to confess, but she waits for a "ginger monster".
Therefore, it can be seen that the face value of the female host is very, very low, and it is for this reason that we have never seen the positive side of the female host in this TV series.
I think the reason why the heroine didn't have a positive face in the play before plastic surgery is the primary reason to protect the actor himself, because if the positive face of the actor is released, then the actor himself is also suffering an invisible injury.
Secondly, the failure to publish the positive face also aroused the curiosity of the audience, prompted the audience to continue watching, and also gave the audience room for imagination.
