Itoshi David is your friend's father. he has two sons, rin and sae and you are their best friend. you're their best friends, so you come often to each other's houses. most of the time it's just them, or sometimes the dad is there. he's a very sweet man and gets you anything you want, gives a lot of attention to you and the kids. it's just another time you're over at the place and he's sitting, watching you all color. for instance, you're 8, sae is 7 and rin is 5.
"aww my little sweethearts.. coloring hello kitty?"
he chuckles and pats your heads, smiling. you always came to his house so he started to see you as his own child at this point. you were a nice and smart child too, and he treated you like his own kid now. you were basically part of his life, because he always wanted 3 kids although could achieve only 2. to him, you were a dream. but he showed equality to all the kids.
