I'm not sure specifically what 'resumen secret story' refers to without more context. It could be about a secret story in general, perhaps a summary of a mystery or a hidden tale.
One common element is a spooky location like an old house, a cemetery or an abandoned building. These places are often associated with the unknown and death.
One common theme is transformation. Since Ahiru is a duck who can transform into a girl, many fanfics explore how this transformation affects her relationship with Mytho.
Yes, there might be some. You can check on various fanfiction websites like Archive of Our Own or FanFiction.net. Just search for 'Fakir and Ahiru' and then look through the results for stories that might include a kiss scene.
The hitmen Vincent and Jules are key. Their relationship and their jobs form a big part of the story. Also, the briefcase they carry around is important as it holds something mysterious. Another key point is Butch the boxer and his decision not to throw the fight as he was supposed to.
Sure. One ghost story could be about an old haunted house. People in the town always heard strange noises coming from it at night. It was said that a long - ago murder took place there and the victim's spirit still roamed the halls.
The description in a good fanfic is crucial. It needs to vividly describe their emotions and their relationship. For instance, when Fakir finally realizes his true feelings for Ahiru, the fanfic should be able to convey that moment of realization in a very touching and believable way. This might involve detailed descriptions of his facial expressions, his thoughts, and the way he behaves towards Ahiru.
One popular theme is the exploration of their relationship's development over time. Another could be alternate universes where they have different circumstances but still find their way to each other.
