摘自本作简介中该角色的段落

【Protagonist's Older Brother】 He is a very caring and honest man. Their father passed away when they were young, so he took up part-time jobs since his school days to support their family and make life easier for their mother, all while maintaining a clean record at school. During his student years, he achieved excellent academic results, but he chose not to pursue higher education and instead started working, all to ensure their mother's comfort as quickly as possible.
