The theme of identity can be interesting too. Shinichi's dual identity as Conan often plays a role. Fanfictions may explore how Ran starts to suspect something is off with Conan and how Shinichi tries to keep his identity a secret while still being close to Ran. This adds an element of intrigue and drama to their relationship in the fan - created stories.
One common theme is the exploration of their hidden love. Since Shinichi is often in his Conan form, there's a lot of unspoken tension and longing between them in these fanfictions. Another theme is teamwork in solving mysteries. They often work together to crack cases, and this shows their strong bond.
One of the common themes is trust. Ran has to trust that Shinichi will come back to her, and Shinichi has to trust Ran with his secrets. Also, the theme of sacrifice comes up. For example, Shinichi might sacrifice his own safety or time to protect Ran. And of course, the theme of reunion is also there, as they are constantly in a state of being apart and then coming back together.
In a fanfiction, perhaps Shinichi and Ran are on a school trip. They get separated from the group and find themselves in a beautiful, secluded spot. Shinichi looks at Ran, realizes how much he loves her, and leans in for a gentle kiss. This simple yet profound moment could be a turning point in their relationship, with Ran finally getting the affection she has been longing for from Shinichi all this time.
One common theme is friendship. Their bond as detectives and friends is often explored, showing how they rely on each other, trust each other, and grow together. For example, in many stories, they will share their deductions and work together to solve difficult cases that neither could solve alone.
In many Detective Conan fanfictions, a kiss between Shinichi and Ran is a highly anticipated and emotional moment. Some fanfictions might have this happen during a dangerous situation where they think they might not make it out alive. For example, when they are trapped by a villain and in that moment of despair and love, they share a kiss. It's a way for fans to explore the romantic side of their relationship that is often hinted at but not fully realized in the original series.
Rivalry is a very common theme. Kaito Kid and Shinichi are both highly intelligent characters, so their battles of wits are often central to the stories. For example, in many fics, Kaito Kid will plan a heist and Shinichi will try to stop him, creating a tense and exciting dynamic.
Another idea is that they are at a masquerade ball. Shinichi is disguised as someone else, but Ran still senses his presence. They dance together and as the music reaches a crescendo, Shinichi reveals himself and kisses Ran. This would add an element of mystery and glamour to the story, as they are surrounded by other masked guests who are oblivious to their true identities.
One common plotline is that Shinichi finally reveals his identity to Ran completely and then they kiss. This is a big moment because in the original series, Shinichi's identity is a huge mystery for Ran most of the time.
The theme of sacrifice also appears frequently. Shinichi and Ran are often willing to sacrifice their own time, hobbies, or even career opportunities for the sake of their baby. In some fanfictions, Ran gives up a big job offer to be a full - time mother, while Shinichi reduces his detective work to be around the family more. These themes together create a rich tapestry in 'shinichi and ran baby fanfiction'.
One common theme is the mystery of their relationship. Since Shinichi has his detective work that often takes him away, there's always a sense of mystery about when he'll be fully present in Ran's life in a lot of fanfictions.
