In the fanfiction, Naruto might comfort Temari by simply being there for her. He could offer her a friendly shoulder to lean on and listen to her problems without judgment.
If Temari is feeling stressed about her role as a shinobi in diplomatic matters, Naruto could offer his own perspective. He might say 'I'm not always good at the political stuff either, but I've learned that being true to yourself and your village is the most important thing. You're doing great, and everyone can see your strength and determination.' This would boost Temari's confidence and comfort her in her role.
Temari might respond with a mix of annoyance and amusement. At first, she could be put off by Naruto's flirting, seeing it as too forward or silly. But then, as she gets to know him better, she starts to be more amused and might even flirt back a little, showing that she's starting to enjoy the attention.
