thinking about how tetsu was probably the most supportive adult/mentor figure in sumio's entire life and the only one whos ever shown him compassion and treated him as a person and as an equal, thats why sumio mirrors a lot of what he does, even down to the random aggressive outbursts and swearing that tetsu's known for before he goes back to masking as his calm and collected self 😭 clearly his parents were absent, the adults of mikumo were a lost cause, it's just him and his 3 friends in their paradise and the power-hungry zaibatsu destroyed that paradise to the ground and the adults that were supposed to protect these children failed them. tetsu's gesture to buy him that suit the first time they met, that was the first time sumio's ever been given kindness (even if that was probably just a simple empty jab from tetsu)
