i thought that was his brother with the blonde hair
That's another possibility
he said they were cousins not brothers
hyung is just a general honorific that a younger person was to an older male

I think he had a twin brother who was a lot closer to nabi than him, and then out of jealousy he probably tempted to murder his brother but was unsuccessful. And now his parents live with the brother to take care of him (who is probably disabled in some way now).
