Well, usually when we hear 'John Doe', it's more of a fictional or anonymous reference. But there might be rare cases where it refers to an actual person if it's in a very specific and local context that we don't know about.
I haven't actually read this particular fanfic in full. But generally, in fanfics about John and Seraphina from 'unordinary', the relationship between the two characters can be explored in many interesting ways. Maybe this fanfic focuses on their friendship or a potential romantic relationship in a unique setting within the 'unordinary' universe.
Since there's not enough information about which 'John Doe real story' is being asked, it's difficult to give a very detailed answer. However, it could also be a story about a John Doe who was involved in a historical event. Maybe he was a witness or a participant in a significant local or even national event, and his actions or experiences during that time are what make up the 'real story'.
John Doe was an ordinary gamer, but one day, while playing his favorite game, he discovered a hidden quest. He embarked on this adventure, facing various challenges. Along the way, he met a group of fellow gamers who became his friends. They fought together against powerful bosses and overcame numerous obstacles, all while having a great time in the virtual world of the game.
The names John Doe and Jane Doe are typically used as generic names for unidentified individuals. Without further details, it's difficult to tell the real story. It could be a story about two ordinary people in a small town, or perhaps they are used in a legal or mystery - related context where their true identities are being concealed for some reason.
One great 'Unordinary John x Seraphina' fanfic is 'A New Bond'. It explores their relationship in a post - school battle scenario where they have to team up against a new threat. The way the author develops their characters and the chemistry between them is really engaging.
