Manhwa based fics??

I dont know if im not looking hard enough or whatever but i feel like the fan fictions for manhwas that i read (specifically historical isekai) dont have many/any fics. does anyone know why? i feel like theres so much to expand on in heaps of these stories or just situations that characters could find themselves in that people just arent writing about.

If anyone asks why dont i write fics, its because i dont have the skill, the tolerance or the commitment to write a fic, i could write a short one...... but i also hateeeeee writing with a passion. im a reader through and through (๑•ㅂ•)و✧
