There are indeed such fanfictions. In the world of 'Harry Potter' fanfiction, the relationship between Harry and Hermione is a popular topic to explore romantically. Since they are two of the main characters and have a deep friendship, it's not surprising that some writers choose to have them kiss in their fictional works. This allows for different interpretations of the characters' relationships beyond what J.K. Rowling originally wrote.
Well, it depends on what you consider 'good'. There are many fanfictions about Luna and Harry kissing. Some focus more on the romantic build - up, while others might be part of a larger adventure story where the kiss is just one moment. You really have to dig in and read a few to find the ones that suit your taste.
There are. A lot of fanfiction writers are attracted to the idea of Harry and Tonks having a romantic moment like a kiss. In some fanfictions, it might be a spontaneous moment during a dangerous adventure, while in others it could be a more tender, slow - building relationship that leads to that kiss.
In Harry Potter fanfiction, a 'poisonous kiss' could be a creative and often dark or dangerous plot device. It might involve a kiss that has a harmful magical effect, perhaps used by a villain to incapacitate or harm a character. For example, a dark wizard might use a poisonous kiss to put a curse on an unsuspecting victim, like a love spell gone wrong that instead of bringing love, brings harm.
There are likely some out there. Fanfiction platforms like Archive of Our Own (AO3) might have such works. However, this kind of relationship is not canon in the original 'Harry Potter' series. Some fanfictions with this theme could explore an alternative or AU (Alternate Universe) take on the characters' relationships, but it may also be a rather niche or controversial topic among fans.
There are several fanfictions out there where Hermione kisses Harry. One popular one is 'The Secret Love' where they share a passionate kiss during a magical adventure.
In some fanfictions, after the kiss, they become more awkward around each other at first. Harry might be worried about how his friends will react, especially Hermione who has been a bit critical of Cho in the past. Cho, on the other hand, might be worried about what her Ravenclaw friends think.
There's 'A Different Path' which is quite popular. In this fanfiction, the story takes a different turn from the original series and Harry and Hermione's relationship blossoms into a romantic one, with their kiss being a significant moment. 'The Hidden Affection' is also a great one. It delves deep into their characters and shows how their relationship could develop romantically, including some really well - written kissing scenes. But keep in mind that everyone has different ideas about what makes a 'good' fanfiction.
