Such fanfiction goes against the family - friendly nature of the original works and can also be considered disrespectful to the creators' intentions.

One great fanfiction idea could be them sharing a picnic by a beautiful waterfall. They could talk about their dreams and how far they've come together. This would be a really sweet and innocent moment that shows their deep connection.
