There's a fanfic called 'Shared Stages'. In this story, Blaine and Rachel are both in New York trying to make it big. They start as rivals but gradually become friends who support each other in auditions and performances. It's a really heartwarming read that shows their growth as characters.
One popular trope is the 'unlikely friendship'. Since they have different personalities and musical styles in the show, fanfics often explore how they can form a deep and meaningful friendship. For example, in many stories, they start off not getting along but then find common ground in their love for performing.
Another option is Wattpad. Although it has a wide variety of content, you can still find some interesting Glee fanfictions featuring Rachel and Blaine. You may need to do a bit more searching compared to the other two platforms, but it's worth a try.
One great story could be about Rachel and Blaine teaming up for a musical performance that changes their relationship dynamics. They might start off as rivals but through the process of rehearsing, they develop a deep friendship and mutual respect.
A common and interesting plotline is their collaboration on a Broadway - style musical production. They could be the leads and have to work through their different acting and singing styles. Blaine might bring his charm and smooth vocal style while Rachel's more powerful and diva - like presence creates a contrast that they have to blend together for the success of the show.
One type of non - sexual Blaine and Rachel fanfiction could be centered around their rivalry in a singing competition. Maybe they both enter a local singing contest outside of school and initially see each other as threats but gradually come to respect each other's talents. This can lead to a story full of humorous exchanges, moments of self - discovery, and the growth of their relationship as fellow performers.
One popular Glee Blaine sick fanfiction is 'Under the Weather'. It beautifully portrays Blaine being sick and how the other characters, especially Kurt, take care of him. The story focuses on the tender moments between them during his illness.
I'm not sure if there is specifically 'glee blaine abused' fanfiction. Fanfiction can cover a wide range of themes, but abuse is a very serious and often disturbing topic. The 'glee' fandom generally focuses on more positive aspects of the characters' relationships, like friendship and romance, so it might not be a common type of fanfiction within the fandom.
Another option is Tumblr. There are many Glee fanfic blogs on Tumblr. You can search for tags like #Glee #Blaine #sickfanfiction. Some bloggers also post links to their own fanfictions or recommend ones they've read. However, the search on Tumblr can be a bit more hit - or - miss compared to the other two platforms.
Friendship - turned - love is also a popular theme. They start as friends or just acquaintances in the Glee club context, and then gradually their relationship evolves into something more romantic. For example, in some fanfics, they start by competing against each other but end up falling in love.
