Welcome to the Classroom Where Passerbyism Comes First

What is the definition of high school student? Save the world? Or can you spend your youth freely and fall in love with many cute girls? This kind of life, this kind of life should be the protagonist! Then all this has nothing to do with my role as a passerby. I... Am just a passerby with no sense of existence, no strong strength, and no handsome face. That's right, that's it. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
