Novel, I saw that you are writing quite a lot and it's fun to see your stories. Sederhana, tapi menarik. But if I could give you an advice, this is how you put a dialogue in narrative stories:

"Saya tidak suka." ucapnya.
"Apa maksudmu?" ia bertanya bingung.
"I don't like you," she screams.

Jadi, you don't have to put any dots (.) atau tanda baca lainnya setelah penutup ("). Hope that helps!
