They're not blood-related. The mc's parents died in the car accident. He was only adopted (not really since he's not on the family register) because he is the son of the ml's father first love. His mother is ml's father first love but he has a different dad. ML's parents are arranged, the man couldn't marry his first love (mc's mother). The only wrong about here is that the ml literally raised mc but they're not blood related.
Yeah, in the eyes of the readers and mostly people around them but on the law, they're not. I was just answering your question if they're brother which is not if we're talking about blood but yeah technically they are. Still at the end of the day, it's still wrong since the ml raised and saw mc since he was a child.
Everything about this is beyond wrong, YALL aren’t they brothers…? I wish stuff like this would give a warning and most of other Bl stuff
