Just great, this might be another dropped series for me, if the new "summon" becomes a central part of the story. It is, perhaps, one of the most irritating tropes in all manga/manhwa/anime to have a summon that treats the MC like crap, treats his friend worlds better, causes nothing but trouble and grief, and just doesn't listen to him, all while talking down to him constantly. He'll probably act smug and arrogant when he helps the MC, or exact an annoying price for doing so as well. I'm wildly disappointed, seeing as I was actually enjoying this series before the fiery asshole showed up.
