A fanfiction could focus on Sakura and Syaoran's daily life after the main events of Cardcaptor Sakura. Maybe they are training new cardcaptors. They could be facing challenges like how to teach the newbies about the importance of the cards and the right way to use their magic, all while their relationship continues to develop in this new phase of their lives.
Adventure is also quite common. Fans like to write about Syaoran going on different adventures, either related to collecting cards or something completely new. Growth as a character is another theme. Fanfictions often show Syaoran growing, becoming more powerful, and maturing both in his magic skills and in his relationships.
For Tomoyo, she might be overjoyed as she has always been supportive of their relationship. She could see this kiss as a sign of their relationship deepening and might start planning more things for them, like new outfits for their future 'dates' in card - capturing adventures.
Perhaps it's a goodbye kiss. Syaoran has to leave for a while, and in a very emotional moment, they kiss. It shows their deep love for each other and the pain of separation. In the fanfiction, this could lead to a series of events where Sakura is constantly longing for his return.
Love is a very common theme. Since they have a special connection in the original series, fanfictions often explore the growth of their love. Another theme is adventure. They are both involved in magic, so new adventures are often written about. For example, they might go on a quest to find a lost Clow Card.
One interesting fanfiction could be about Sakura and Syaoran going on a new adventure together in a parallel world. They might face new Clow Cards or some other magical threats. In this story, their relationship could grow even deeper as they rely on each other to overcome difficulties.
Perhaps in the fanfiction, there's a parallel universe where Sakura and Syaoran are enemies. They have to figure out what has gone wrong and how to set things right. This would involve a lot of self - discovery and exploring the nature of their relationship in different circumstances. They would need to find a way to break the spell or whatever is causing this rift between them and restore their normal relationship in their own universe.
One great fanfiction could be 'Syaoran and Sakura's Unseen Adventures'. It might explore their relationship further after the events of the original series, like how they deal with new magical threats together. Another one could be 'Sakura's Heart, Syaoran's Love' which might focus on the emotional depth of their connection, perhaps with Syaoran expressing his love for Sakura in new and different ways. And 'The Magical Bond of Syaoran and Sakura' could show their bond growing even stronger as they face challenges that test not only their magic but also their relationship.
There's a fanfiction where Sakura and Syaoran get trapped in a time loop. Every day they wake up and have to relive the same day over and over again. At first, they are confused but then they start to notice small details that are different each time. As they work together to break the loop, they learn more about their own powers and their feelings for each other in a really unique way.
One great 'Cardcaptor Sakura Syaoran' fanfiction is 'A New Adventure for Syaoran'. It continues the story with Syaoran on a new quest related to his magic. Another one is 'Syaoran's Hidden Feelings' which delves deep into his emotions that he might not have fully expressed in the original series.
