Film and TV Crossover: Cling to the Male Lead’s Best Friend

A fanfic with original female leads set across various TV series, with a touch of the adored-by-everyone trope. The male leads have a high proportion of supporting characters (falling for the second male lead is my fate). There may be canon-pairing breakups and multiple male leads, so beware if that's not your thing. I like revisiting old favorites. These are all shows I personally enjoy, and liking the supporting characters may just be my fate. The story will mostly follow the original plots, and the female lead will interact with the original protagonists. Her greatest golden finger is her identity. She may not be human: spirits, immortals, demons, and all sorts of beings are possible. Coming up (not necessarily in this order, but these will mostly be included): The Mystic Nine: Fo, Si Ultimate Note: Hei, Hua Joy of Life 2: Ze, Xian, Qian A Journey to Love: Li Tongguang My Journey to You: Jue, Zhi Mysterious Lotus Casebook: Di, Fang, Hua
