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.
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.
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.
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.
Well, a great Bolin x Asami fanfic might involve a plot where Bolin tries to court Asami in a very traditional and clumsy way. He could be taking advice from all his friends, but things keep going wrong in a humorous manner. For example, he might plan a grand dinner but accidentally sets the table on fire. Or, it could be a fanfic set in an alternate universe where they are both part of a resistance group against an evil regime. Their relationship develops as they fight side by side and rely on each other's strengths.
Well, family is a big theme. Their relationship as brothers is central to most fanfics. Growth is also common. We see them growing as characters, learning from their experiences. And of course, friendship. Even though they're brothers, their friendship - like relationship is often explored, like how they support each other's dreams and goals in different fanfics.
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.
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.
Well, it's also about the exploration of the Legend of Korra universe in a different way. By changing Bolin's sexual orientation, it can lead to different storylines and interactions with other characters. For example, his friendships might develop into something more romantic, and we get to see how that affects the overall dynamic in the Avatar world. Also, it gives fans a chance to see Bolin in a more vulnerable and complex state, which can be really engaging as we get to know more about his inner thoughts and feelings.
