The best architect is Sumeru, who does not brag about his position. Deep emotional wounds and feelings of guilt still torment him. But he clearly knows how to hide emotions. Does he always have a radiant smile? No one would even guess how much pain his eyes store. He does not know how to accept help, but strive to help everyone. Because of him, in his opinion, his father died, mired in the quicksand of the desert. After that, his mother fell into depression, and then left Kaveh, saying goodbye.
