To Protect Myself, I Became the Big Brother of Technical Secondary School

As the eldest brother of a technical secondary school, I never write an introduction. Good text is the key. As the eldest brother, we cannot be scumbag, so it is a single heroine. Am I affectionate and dedicated? It is difficult to make up 100 words. As the eldest brother, I feel that I cannot compromise.,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, This novel and its characters are purely fictitious.
