The trick to write heated arguments, fighting scenes, or tense situations is showing the reader instead of writing what's happening.
A dialogue that "writes" what happens:
Lorea arrived at the Comiket and finally saw the person she was searching for. Lorea was angry and shouted. "You there! Why did you sneakily take photos of me?"
The woman turned around and showed a surprised expression. "What are you talking about?"
Lorea snorted and walked up to her with quick steps, looking angry. "You know what I'm talking about. Now, delete every photo right now!"
Same dialogue but "shows" what happens.
'I've been searching around the Comiket and couldn't find her. Did she really leave?' Lorea felt uncomfortable. Her eyes moved to the side and spotted her. "You there! Why did you sneakily take photos of me?"
When she saw the furious person approaching, the other woman felt her heart tightening while remembering what she had done previously. "What are you talking about?"
Lorea's blood boiled. "Hahaha! Do you really think you can play stupid with me!? You know what I'm talking about. Now, delete every photo right now!"
In short, adding emotions, thoughts, and writing the physical feelings gives the read much more depth. Using these tricks, you can create an intense argument without resorting to cuss words.
