Yes, there are likely some popular ones. Often, these fanfictions gain popularity because they explore the relationship between Mako and Korra in a way that the original show might not have fully delved into. For example, some might focus on the emotional build - up to the kiss, which can be really engaging for fans who are invested in their relationship.
The 'lemon' aspect might be a bit hard to come by in a clean way as it often involves inappropriate content. But for normal Korra and Mako fanfictions, you could also try FanFiction.net. Some stories there might show their relationship developing, their adventures together, and how they support each other, which can be really interesting to read.
Common themes include the power of love. Their kiss can be seen as a moment where love overcomes all obstacles in their path. There could also be a theme of redemption. If one of them has made a mistake in the relationship, the kiss can be a sign of forgiveness and a new start. Additionally, the theme of discovery is often there. They discover new aspects of themselves and each other through their relationship, and the kiss is a part of that exploration.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like Archive of Our Own. There you'll find a variety of stories with different plotlines involving Mako and Korra's relationship, including some with their kiss as a significant moment. Some stories might focus on their relationship development before the kiss, while others might explore what happens after.
There could be a fanfiction where the kiss is a moment of impulse. Mako and Korra have been through a lot, and the emotions just build up until they can't hold it back anymore. This could then lead to a series of events where they have to deal with the consequences of this sudden display of affection, like how it affects their friendships with others in the group.
Archive of Our Own is a great place to start. It has a large collection of fanfictions, and you can easily filter out any inappropriate content. Just search for Korra and Mako, and you'll get a variety of stories exploring their relationship, from friendship to romance, all within the boundaries of a proper and respectful narrative.
One common theme is love against all odds. Since Mako has his own set of challenges and responsibilities in the show, the OC often has to navigate through those to be with him. Another theme is the discovery of self - worth. The OC usually starts as an underdog and through the relationship with Mako, they find their place in the world of the Avatar.
Love is a big emotion. Even if it's just the start of their romantic journey, there's an underlying love that has been growing. There could also be a sense of relief, like they've finally let their true feelings show after holding back for so long. They might feel a bit giddy and happy, like they're on top of the world in that moment.
Well, there are fanfictions where the OC has a unique backstory. For example, an OC who was once a part of a circus troupe and has acrobatic skills. When she meets Mako, he's initially skeptical of her but as they get involved in the Avatar's adventures, he comes to admire her tenacity. Some fanfictions focus on the romantic aspect right from the start, with Mako being instantly attracted to the OC's kind heart and beauty.
It's important to note that many fanfiction communities strive to maintain a family - friendly or at least a PG - 13 kind of environment. So, while there could be Korra and Mako fanfiction, the likelihood of finding one with a'make love' scenario is low, and it may not be in line with the positive and respectful nature of the fan community.
