What Do You Want In Life

I havent read it but it wasnt rly long and i think it was either shounen/shoujo/josei.. anyway so the main guy gets stuck inside a manga he himself made and meets the heroine (long dark hair i think) there and develops feelings for her (maybe) or just starts caring towards her ,but since he wrote the manga so he knows her fate and it aint good , so hes stuck in a dilemma ... Can anyone help im dying here ┗( T﹏T )┛

Hi this is my very first time using this question box.
Ive been experiencing very unfamiliar feelings rn. Im a girl and idk or im not sure if im having to my friend who’s also a girl. Can someone pls grant me some experiences or advices? I think i just need someone to talk to cuz ive never ever disgusted about these with any of my friends since im straight until now.
