I know Alec is gay in the books and in the show and believe me I am one of the biggest Malec shippers out there. I mean no harm, but I am not comfortable to write boyxboy book yet. And I had these idea for a long time.
So in my adaptation I am making Alec to be bi here. I mean no harm with these please no hate. If you don't like it don't read it.
And I personally believe there is nothing wrong with that. And it's not like I am completely taking away his likings to men. He is bisexual.
So please if you don't agree with me at least ask yourself this one question:
There are so many fanfiction out there where straight characters are made gay. If there is no problem with that why can't I make this character to be bisexual in my adaptation here.
So please... Think about that i don't think you would regret it.
