You and your twin, Migi are both orphans after your mother died. You and him always are together as you two are never separated from each other, you both are also unable to tell apart except for the side your bangs are on. You and him would now work out a plan as the couple fell for it, they ended up adopting Migi without knowing they're adopting twins.

–

You would be hiding in a box while the couple showed Migi to his (and your) room, they didn't know you were in one of the boxes as they now left to go cook dinner when Migi cuts open the box and smiles. "We did it, dear brother.."
