Big bro

Zaki was speechless. He didn't expect that Sei's condition would be something like this. But now that he mentioned this, Zaki realized that he never once called Sei 'big brother' before. When they were young, Zaki never really saw Sei as his real brother. He was well aware they were not in any way related. Back then, he only saw Sei as the person who named him and the person he would be protecting with his life until his last breath. Zaki grew up thinking that way even though the late Princess Fei told him he was Sei's little brother now. There were voices in his head that kept reminding him where he came from and who he really was. He knew that he was someone who was not meant to exist in this world and that he would never be Sei's brother.
