Another plot could involve female Naruto's friends noticing her crush before she's ready to admit it. They might try to play matchmaker, which could lead to some awkward and funny moments. For instance, if her friends think she has a crush on Kakashi, they could set up situations where she has to be alone with him, like 'accidentally' leaving them together during a mission briefing. This would force female Naruto to deal with her feelings in unexpected ways.
A more complex plot development could be that the object of her crush is in a difficult situation, like being targeted by an enemy. Female Naruto, driven by her feelings, decides to put herself in danger to protect them. This would not only show the depth of her crush but also her growth as a character. For example, if Shikamaru is the one she likes and he's captured by an enemy ninja group, female Naruto could embark on a solo rescue mission, facing many challenges along the way and realizing just how strong her feelings for him are.
