If Naruto doesn't return her feelings, it could potentially damage their friendship. Sakura's confession might make Naruto feel pressured, and he may start avoiding her. However, if they communicate openly about it, they could potentially salvage their friendship and even grow closer in a different way. For example, they might become more honest with each other about their emotions in general.
In some fanfictions, a great plot twist is that Naruto has amnesia when Sakura confesses. He doesn't remember who she is or their past interactions. This makes Sakura's confession even more poignant as she has to try to make him remember and also deal with his possible rejection. Also, there could be a time - travel plot twist where Sakura from the future comes back to confess her love, which throws Naruto into a state of confusion as he doesn't understand how this could be possible.
Often, Sakura is initially shocked. She may have always seen Naruto as a friend or a teammate. But then she starts to recall all the times Naruto has been there for her, like when Sasuke left and Naruto promised to bring him back. This makes her re - evaluate her feelings towards Naruto. Sometimes in fanfiction, she accepts his love right away, while other times she needs more time to think.
However, in other cases, Naruto could be hesitant. He might have grown so used to their friendship that the idea of a romantic relationship with Sakura is a bit overwhelming. He could take a step back and say something like 'Sakura, this is really unexpected. I need some time to think about this.' This would then lead to a more complex exploration of their relationship in the fanfiction.
One heart - touching moment is when Naruto bares his soul during the confession. He might talk about how Sakura's smile has always been his motivation. For instance, in a dangerous battle, seeing her smile in his memories gave him the strength to keep fighting. Another moment could be when he gives her a meaningful gift during the confession, like a flower that has a special significance in their shared past.
In some fanfictions, Sakura might confess to Naruto in a very emotional and private moment. For example, perhaps after a dangerous battle where they both almost lost their lives. She could pour out her long - hidden feelings, saying how she has come to truly see Naruto for who he is and not just the annoying kid from before.
One scenario could be that Naruto is initially shocked but then quickly realizes his own feelings for Hinata. Another might be that Hinata's confession causes a stir in the village as it's a very public event. Or perhaps Naruto is in the middle of a difficult mission and Hinata's confession gives him new motivation to succeed.
She might be shocked at first. Given Sasuke's past coldness towards her, it would be unexpected. But then she would be overjoyed. After all, she has loved Sasuke for a long time. She would probably start crying tears of happiness and immediately accept his confession.
They might be characters created specifically for this fanfiction. Alice could be a shy and kind - hearted girl, while Mirana could be a strong and independent figure. Their different traits would make the story of Alice confessing her love more interesting.
