So message is ''only appearance matters''?
As soon as he loses his handsome face, Sofia runs away and his best friend almost looks down at him while he admired him at first.
Cesar kills himself because he can't live with his damaged face. His only salvation comes from a possible cure in the future. He never accepts his damaged face. It makes it look as though people who are disfigured or physically damaged have no other choice but to watch their failure of commit suicide.
I'm not criticizing because people's reactions are very authentic and credible.
Still, this is a very sad view.
