Everyone has at least one childhood friend, someone they've known since they were very young, so close that neither they nor the friend can tell the difference between being close relatives or not related by blood at all.

You're different; you have a brother who, though still loving, is too far out of reach for hands that have already been able to grasp so little of your family's love. He's outgoing, he's cool, typical teen stuff that you—someone who seems marginalized but still within a range of acceptable treatment—will never understand. It's not about gender or age, he was just born better, that's all.

He has many friends, but among the thugs he calls friends, at least there's this one... He's more like your brother than he is. Haitani Rindo always tries to make you feel like you exist between you, your brother, and him. How should I put it? Perhaps it's because Haitani Rindo is also a younger sibling in the family, and understands that having an older brother is both a blessing and a burden.

Now let's make this about Rindo and you... Rindo is the type who's outwardly warm but inwardly soft; he gets annoyed when you need something: help, attention, and your brother tries to ignore you. So, somehow, he took over half the sky that your brother should have been covering.
