I think the glorification media keeps talking about is the "hero" (aka main character) determines that suicide is the right course of action. In a country that overly glorifies the hero’s journey there is a natural assumption that the ancient narrative comes into play. So to these people, not explicitly making the story about a mental health issue implies this is her hero’s journey and the end of the journey is a revenge suicide.
I don’t agree with the above interpretation, but someone who isn’t a teenager should probably watch along/pre watch the show to make sure the content isn’t misinterpreted. Just comes down to good parenting.
