FMAB: The Eldest Elric Brother

[Fullmetal Alchemist Brotherhood fanfic ~FEMALE REINCARNATED INTO A MALE OC WITH GAMER ABILITIES~]
When a female fan gets reincarnated into her favourite anime, she is...conflicted, for a number of reasons:
One: She, a retired genius surgeon famous for her emotionless facade died, leaving her peacefully boring life of reading behind.
Two: She was reborn as a male, tool and all.
Three: She--Well, I guess it's he now, is the first born son of Trisha Elric and Van Hohenheim. A full 8 years before Edward Elric's birth.
Four: He is bound by a game system, and to top it all of he's still straight...or is it bent now?
Five: He is neither kind nor selfless, but he is willing to be if he gets to see a good story play out.

A story of a reincarnated soul that rather live freely than save a country or his family (But is that really his true face?)

NOTES:
- OC personality: I won't spoil it, I'm just going to say it's NOT a "I'm going to save everyone but get guilt in the end" or "I'm going to be all stubborn and curse a lot, I rather save my a** then others so run away from the plot," or "I'm the classic female heroine that everyone loves and needs saving or mental support."

Warnings: Mostly Censored Cursing (Edward), yaoi, OC (only one), there MIGHT be mature scenes in which a warning will be placed at the beginning of the chapter (though "MIGHT" is a keyword since I'm still thinking about it.) I don't own any videos or pictures I may use (unless I claim them since I do draw occasionally) (FYI, most images are slightly edited by yours truly.) (Still belongs to whoever drew them). Non-existent update schedule.
