Good Bi Rain and Reader fanfic often has a strong sense of characterisation. It should capture the essence of Bi Rain's charm and persona. The relationship between Bi Rain and the reader - insert character should be developed in a believable way, not too rushed.
I'm not entirely sure which specific Bi Rain and Reader fanfic are out there. But usually, when looking for such fanfics, it's important to check multiple fanfic communities. Some Tumblr blogs might also have people sharing or creating Bi Rain and Reader fanfic. You have to dig a bit and look for tags related to Bi Rain and the concept of reader - insert stories.
One common theme could be the journey of a fan meeting Bi Rain and the adventures that follow. It might involve the fan getting to be part of his music video or concert in a fictional story.
There could be a wise old mentor figure. This character might be an elderly person who has a lot of knowledge about the world that Go and Rain Bi are exploring. For example, in a fantasy - based fan fiction, this mentor could teach them magic spells or give them advice on how to defeat the evil forces.
I'm not sure specifically which 'Bi Rain and You Fanfic' stories are good as it depends on personal taste. However, you can try searching on some popular fanfic platforms like Archive of Our Own. There might be various stories that explore different relationships and scenarios involving Bi Rain.
There could also be themes of power and protection. Damon may be in a position of power in some way, and how he uses that power in relation to the daughter figure, whether it's to protect her or potentially misuse it, can add a lot of depth to the story. Also, the exploration of the daughter's bisexuality might involve themes of identity formation and the search for true love in a more inclusive sense.
One great fic could be where the teen reader is really nervous about coming out as bi to Dean. Dean, being the understanding character he is, gives the reader a big hug and tells them it's okay. He might share his own experiences of accepting different people in the past, which helps the teen feel more at ease.
Perhaps the 'damon x daughter reader' is a way of indicating a close relationship, not necessarily a romantic or inappropriate one. The 'bi fanfic' part might suggest that the story is inclusive of bisexual characters or themes. It could be that Damon is protecting the 'daughter' character in a world where bisexuality is either accepted or discriminated against, and the story is about their journey together through different situations related to this.
Another option is to join relevant fanfic groups on platforms like Discord. Members in these groups usually have a passion for the same type of fanfic and might be able to point you in the right direction. They may even have their own collections or favorites that they can share with you.
Self - discovery is also common. The process of the teen coming out as bi is part of their self - discovery journey, and Dean can play a role in helping them understand themselves better, like by asking the right questions or sharing relevant stories.
