This reaction was entirely expected of yeon tbh. Throughout this entire story, there has not been a single moment when he has respected yeomin as a human being. Yeomin was never anything more than a convenient hole for him, and an item to be possessed. His motives for "helping" yeomin were always selfish, and the ways in which he went about "helping" were toxic. A half decent person who cares about yeomin even a little bit would have been happy he finally had the chance to have a social life (especially one that seemed to genuinely make him happier), but even that only frustrated mr yeon. He was always toxic and abusive, and for that, he needs to be knocked down a whole lot of pegs.
