AFAIK (pls CMIIW), the girls around MC are either in love with or admire him. Bcs for them MC is so cool/a genius and caring. But MC never put much thought into their advances bcs he himself thinks he's the weakest of all and therefore thinks the girls were just being kind or friendly to him. It's actually funny to see him struggling with these superhuman girls

does this have harem?
