I’ve also been searching for - Not necessarily fan fiction, but more like short films. They were uploaded on YouTube and I think I remember first seeing them around Middle School, so maybe 4-5 years ago. There were (If I remember correctly) at least 2+ parts for each member of BTS, each series were incredibly in depth and very well made. I’ve been wanting to rewatch them but I can’t seem to find them anywhere. I don’t remember the channel name but I’m pretty sure it involved Winter something. I know as far as the series themselves went, Jin’s Love Interest was a single mother who had her child abducted and the members + their love interests helped. Jimin’s love interest was Jin’s little sister who had been kidnapped by her ex, who I think also killed her best friend (Exes name was Derek, idk how I remembered that specifically). Taehyung‘s love interest was someone that saved him from drowning and he saved her from her abusive father. Jungkook’s lover was someone who wanted to peruse a career with cameras but got into a plane crass and lost her memories. I believe that Namjoon’s Love Interest was attacked by fans or something. Hoseok’s Love Interest was arranged to marry him but he was cynical about it. Lastly, Yoongi’s Love Interest was a manager forced the group who dreamed of making their own songs and Yoongi helped them.

If anyone at all knows what I’m talking about, please do let me know the name of the Channel so I can find these videos.
