Wonder whats really the reason the brother commit suicide

I’ve a feeling he has feeling for his younger brother, that’s why he commited suicide when his brother distanced himself from him. I don’t know, it’s too much of a concidence to kill himself right after having that kind of talks with the brother ╥﹏╥

Ohhh that too alsoo one of the possibilities

I'm assuming an accident.
He doesn't strike me as someone who'd bring pain to others by committing suicide. He comes across as caring and with a bit of a mischievous/playful side. And forgiving. Very forgiving. I don't think he'd die over his brother's words.
