They’re not brothers
Blondie met Yuma at the part and they played a family game together with Yuma’s friend (the blonde girl). Yuma got confused that the blondie and yuma’s friend were both the same person, hence why Yuma doesn’t remember blondie.
Blondie was looking for his real brother until he met yuma’s gay friend (the burnt face dude) which directed him to yuma’s school until he reunited with Yuma.
Can someone explain what the connection is between Yuma and the blonde?? Are they brothers?? Friends?? More?? What is going on y'all
