Reio's Questions (3)

So I remember reading this manga awhile ago
I forgot the title but I remember it's a name of a flower..
It's a phsycological/tragedy
Story goes:
Where this girl moves back with her family to the country
Gets bullied eventually kids burn her house as a prank but things go wrong
Both her parents die while protecting her little sister
Her sister is badly burnt and critical
So she decides to avenge them

-Spoiler here-
She kills hem all or karma gets them
And the one classmate she thought was decent, took pictures of her sister while being burnt
And I don't remember if she's alive at the end or not

I can't find it （/TДT)/

The was this manhwa with great art
where the male MC is an artist that lost his touch
So he listened to his roommate's advice of recording things
Roommate seems to be obsessed with him
And while recording he encounter a person in a crow outfit
Gets inspired
