I just wanna ask if I can write a story that was already seen on tv with a same dialogue… I will copy it, in short.
You can’t, anything you write needs to be your work. It’s a form of copyright infringement, especially using the same dialogue.
You can use whatever you’ve seen on TV as a reference, but your story needs to be significantly different aswell as the dialogue and characters.
If it’s copyright as an original then no
