Well, in many Gakuen Alice fanfictions focusing on Mikan and Natsume's kiss, it's often a very emotional moment. Writers usually build up a lot of tension between the two characters before this moment. For example, they might have Mikan slowly realizing her feelings for Natsume as they go through various adventures together at the academy. And when the kiss finally happens, it's like the culmination of all those unspoken emotions and shared experiences.
In fanfiction, the Natsume and Mikan kiss could be a turning point in their relationship. It could signify a new level of trust and understanding between them. For example, perhaps they've just overcome a major obstacle together, and the kiss is a spontaneous expression of their relief and new - found closeness.
One possible scenario could be during a school event. Maybe it's a dance, and they are dancing together. The atmosphere is filled with a sort of romantic tension. As they look into each other's eyes, they are drawn closer and closer until they kiss.
It could be a dangerous situation. For instance, Mikan might be in harm's way, and Natsume, out of his deep love and protectiveness for her, saves her at the last moment. In the heat of the moment, with all the adrenaline and emotions running high, they share a kiss.
One idea could be that the OC is a new student at Gakuen Alice with a very unique and powerful Alice ability. Natsume, being initially aloof, gradually warms up to the OC as they are paired up for a special project at school. Their relationship starts to develop as they face various challenges together, like dealing with the strict rules of the school and the jealousy of other students.
Here is a simple start for a Gakuen Alice Natsume OC fanfiction. My OC, named Aria, arrives at Gakuen Alice. She is a shy girl with a special alice that allows her to communicate with animals. When she first meets Natsume, he is as cold as ever. But Aria's kind nature starts to slowly break through his icy exterior. She often finds Natsume in the garden, alone with his thoughts. One day, she approaches him and offers him a flower she just picked. Natsume is initially taken aback but then accepts it.
It's Natsume and Mikan. Natsume could be seen as the protector in some fanfictions. He has powers or abilities that he uses to safeguard Mikan. Mikan is the one who gives Natsume a reason to be more than just a loner. The kiss between them is a significant moment that can change the dynamics of their relationship and the story as a whole.
Perhaps in the fanfiction, the kiss is a spur - of - the - moment thing during a dangerous situation. For example, they are in a battle against some dark forces. Natsume, thinking they might not survive, impulsively kisses Mikan. This then gives them new strength and determination to fight on and overcome the danger.
One great fanfiction could be about Mikan and Natsume's first adventure outside the academy grounds. It might explore how they rely on each other's unique abilities to overcome challenges.
