Ye, but this is not giving feedback? This is her going in to change parts of Yeonjoo's story according to her taste?
She's not leaving comments on what part of the story could be change and what may be unnessecary. She just change it according to what she thinks it will be better instead of letting Yeonjoo changes the weak part of her story herself that fits to her style and the story she wants to tell more.
I mean of course the slap is out of hand but, I can understand why she would do that.
Additionally, jealousy is normal, it's a sucky feeling when you've put years into an artform only to have someone just join to automatically do better than you. But it's not like Jeonyoo is actively being hostile or discouraging towards Han Jia.
She even says that Han Jia writing is good to her.
It a sucky period for Yeonjoo and if Han Jia is too scared to talk about it to Yeonjoo, then she should have just let Yeonjoo to figure things out herself instead of doing what she did.
For creator who wants to make art as a career, you have got to be able to handle constructive criticism. You cannot survive when you’re always taking it personally. I will say Jia shouldn’t have done it as a birthday gift. I think she should have spoken with her friend about how she really loves her writing and was concerned for her. Told her she had some ideas on how to make it more appealing to the publisher. But the slap was crazy and the jealousy is out of control. Especially, since Jia is sharing her experiences with her friend and going out of her way to try a promote her friend’s writing. Jia is an airhead but she cared so deeply for her friend and just wanted to help her snap out of her depression episode.
