Rin Okumura
Age: 18
Brith day: April 12 19xx
Sexuality: bisexual
Hobbies: cooking, and taking care of his little brother, Yukio.
More: he's every protective of Yukio, ever since Shiro died. Works two jobs to make ends meet. He'll do anything to make Yukio smile and feel happy. And he doesn't like to talk about his problems. So, he hides them behind his smile. He has a habit of kissing his brother on the head, like a mother.

Picture:

Yukio Okumura
Age: 10
Brith day: March 30 20xx
Hobbies: reading and spending time with Rin.
More: he gets all A's in school. He's very smart for his age. He's working hard in school in order to get a good job when he's older, so he could take care of himself and maybe Rin. Women like to hug him and tell him he's the cutest thing ever, until they stop or Rin saves him.

Back story:
Rin's and Yukio's father went to jail for murder before Yukio was born. Their mom got very sick when Yukio was two, and didn't survive. So, Shiro adopted them. But when Rin was 16 and Yukio was 8, Shiro got into an accident. And didn't make it. Rin being 16 at the time, he became Yukio's legal guardian. The law threatened to take Yukio away from him a couple times. But they didn't take him away for reasons.

~~~~~~~~~~~~~~~~~~~~~~~~~
As you see Rin and Yukio aren't twins in this.
This is a story I'm thinking about.
Hopefully it's good.
Until next time!
