if this is your typical light novel isekai, this kid would be the snobby noble villain who keep boasting about his status and nobility plus talking down on the MC but get kicked the shit of em by the MC later on. But alas, he's supposed to be the 'Male MC' of this Romcom. When the main love interest is written this way, of course reader gonna prefer the other love interests (not naming anyone but, ahem.. Seo Kouji).
