In the fanfiction, Gaston Gil might be involved in a dangerous situation, like being in a fight or getting lost in a dangerous place. His dad, without hesitation, comes to save him. Gaston is initially shocked at his dad's courage and self - lessness. After they are safe, Gaston reflects on how his dad has always been there for him, and he tells his dad 'love you dad'. This kind of life - threatening situation can be a powerful catalyst for Gaston to recognize his dad's love.
One possibility could be a story where Gaston Gil has a difficult relationship with his dad in the beginning. Maybe they had misunderstandings due to Gaston's wild nature. But as the story progresses, Gaston realizes how much his dad has sacrificed for him. Through a series of events, like Gaston getting into trouble and his dad coming to his rescue, they finally reconcile and Gaston says 'love you dad'.
You can try searching on popular fanfiction websites like Archive of Our Own (AO3). It has a vast collection of various fanfictions, and there's a good chance you'll find 'Gaston loves Gil' fanfiction there.
One common theme could be the exploration of their relationship against the backdrop of the original Disney story's setting. It might show how their love develops in a world that doesn't quite expect it.
One possible plot could be that Gaston, after being rejected by Belle multiple times, starts to see Lefou in a new light. Lefou, who has always been loyal to Gaston, is initially shocked but then overjoyed when Gaston shows his affection. They might go on adventures together, with Gaston protecting Lefou from the villagers' mockery as their relationship is quite unusual for the time and place.
Well, it could start with Gaston having a change of heart. Maybe he realizes his wrongdoings and starts to become a better person. Belle, seeing this new side of him, begins to develop feelings. For example, Gaston could start to help the villagers in more meaningful ways rather than just showing off his strength.
For Harry, you could explore his family background more deeply. Maybe he discovers some long - lost relative on the Isle who has a different view on life, which makes Harry question his own actions and values. For Gil, he could be developed by having him learn a new skill, like fishing in a more sophisticated way, which could also give him more confidence.
One idea could be that Harry and Gil go on a treasure hunt that was hinted at in Descendants 2 but never fully explored. They could encounter new magical creatures and face challenges together, strengthening their bond as friends.
Their relationship could be developed through shared challenges. For instance, if they are both tasked with protecting a valuable item from being stolen by a new villain on the Isle. Working together to keep it safe would make them rely on each other more and strengthen their bond.
For Gaston, you could develop his character by showing his vulnerability. Maybe he has a fear of being alone forever, which is why he's so desperate to marry Belle. With Dark Belle, you could explore her darker side more. For example, she could have a temper that she usually keeps in check. You can also have them influence each other. Gaston could make Dark Belle more assertive in a different way, and Dark Belle could make Gaston more introspective.
The relationship could develop slowly. At first, Gaston might not be fully aware of his feelings for Lefou. He might mistake his new - found closeness as just friendship. But as time passes, he realizes that he has deeper emotions. Lefou, on the other hand, has been in love for a while and is patient. They could start with small gestures like sharing a drink or a meal together more often, and then it could progress to more affectionate touches and declarations of love.
