IF YOU WANT TO AVOID SPOILERS DO NOT READ THE NEXT DESCRIPTION OR THE VIDEO PLS SEE THE GAME FIRST! THANK U

My god I love drawing chara!
But seriously through let me talk this straight, why do guys hate so much Chara?
Some people think that Chara is just a piece of trash but I don't know if there are people who understand her, I mean look were she's/he's been through, Chara's species (us humans)
treated her/him like Chara was a curse of bad luck or worse, then Chara wanted to suicide, until Asriel came in and changed her/his life, but she/he still had the feeling she/he didn't desrve all this and ate a buttercup flowerpie and died of poisoning, that's were Asriel sacrificed himself just to achieve Chara's dying wish: to see one more time the flowers of her/his village.
(My god I cried at that part)
But still I know there was still good in Chara inside her heart, is just that, they or more like we didn't gave her/him a chance.

Sorry for that serious moment is just that you can understand what I feel a about Chara.

But it's okay,
CUZ IT'S JUST A THEORY (not rly :/)
A GAME THEORY
