Yuriko could be a healer in Konoha who Naruto meets when he is injured on a mission. As she heals him, they start talking and find out they have a lot in common. Then, they team up to help other injured ninjas in the village during a time of war, showing great courage and selflessness.
Imagine that Yuriko is a talented artist who can draw things that come to life. Naruto is intrigued by this power. They get involved in a situation where an evil sorcerer wants to use Yuriko's power for his own gain. Naruto and Yuriko must fight together to stop the sorcerer and protect the village and Yuriko's power.
The plot could be centered around a mystery. Yuriko discovers a strange artifact and Naruto, being the curious ninja he is, joins her to figure out what it is. Along the way, they face opponents who also want the artifact for their own malicious purposes.
One idea could be that Yuriko is a new ninja in Konoha and Naruto befriends her. They go on a mission together where they have to protect a village from bandits. Naruto's positive attitude rubs off on Yuriko and she becomes more confident in her skills.
Well, often in 'Naruto Yuriko Lemon Fanfiction', the theme of friendship is also explored. Naruto is all about making friends and bonds, and Yuriko could be added to that circle. Their friendship could then develop into something more. Also, the theme of power and growth might be present. Naruto is constantly growing in power in the original series, and Yuriko could be part of that growth story, either by supporting him or having her own power - up journey while being with Naruto.
I'm not really into that specific fanfiction, but you can try searching on popular fanfiction websites like Fanfiction.net or Archive of Our Own. There might be some interesting stories there.
