So it’s basically like a “who will you become in the future card?” He wanted to become a persecutor who would help straighten his brother’s path and stop him from becoming a gangster thus making his mom proud and live a happy life
It was probably like a card he wrote in middle school and attached it to his ID to remember who he wanted to become in the future. I’m gonna cry ╥﹏╥
Ohhhhh so then now mc sees that he was able to make his brothers dream come true :')
Basically ╥﹏╥
Wait who wrote that note on the back of the id card, I don't really remember the beginning other than his brother being killed and it being mushroom's fault
