Another plot could be a high school AU where Hinata is a new student at Gaara's school. Gaara is known as the quiet and mysterious loner. Hinata, being the kind - hearted person she is, tries to befriend him. She starts leaving little notes in his locker with positive affirmations. Gaara is initially suspicious but gradually warms up to her. This leads to them spending more time together, like at the school library studying or at the school garden just talking. Their relationship slowly blossoms in this high school setting.
One plot idea could be that Hinata and Gaara are assigned as partners for a school project. Hinata is initially shy around Gaara, but as they work together, they discover they have a lot in common. For example, they both have a love for art, but express it in different ways. Hinata through her delicate flower drawings and Gaara through his unique sand sculptures. As they get to know each other better, a friendship forms which could potentially turn into something more romantic.
