Y'know, one of the great things about this manga is that it's not pure one-sided teasing. Yes Hino-san wins more often than not, but Koguma secures her fair share of wins too, even if just small ones like in this chapter, "Oh, but I walk to school".
Other manga of this type generally have the main character try to turn the tables on the person teasing them and failing every time. Having Koguma turn the tables from time-to-time keeps it more fresh.
