Karate Baka Isekai

i had liked this manga for a long while where i figured for an isekai manga i could relate to cause it had a main protagonist who had a well focused personality and sought to use his martial arts for good. however, as soon as the 9th chapter comes, one of the characters whos the king and father of the princess who is on good terms with the main protagonist ends up setting something that could be a trigger to a potential love interest between the protagonist and the princess. like, i wasn't expecting a possibly love interest between these characters not that there was any to begin with. the princess sees the protagonist as a teacher and admires him for his martial arts skills and hopes to learn from him which you'd figure it would be like they'd have a teacher and student relationship much later on since the the main protagonist modestly says hes not sure of taking any disciples in the beginning chapters while dealing with the important issues focused in the story and its fitting. but to have a character ship them together by making them marry when they are on complete opposites makes me angry and annoyed especially if you're a reader who at least would like to read one action manga with a main protagonist that doesn't have a love interest at all till the end of the story's debut. love interests and shipping characters is overrated and unfitting and i'd like to read horror and action manga that doesn't have for cool, interesting main protagonists thats put in a romantic-like relationship with anyone especially for an isekai genre where most of that is done so many times.
