The narrator tells us that he ran away because he wanted to get a "heat" around Sebastian. Sebastian realized that the narrator was an "omega" , and Sebastian's reaction was "a complete 180" . The narrator explains that he wanted Sebastian to "prove them all wrong" and "hide the fact that I but was an omega" because he didn't want Sebastian to get caught up in his "lems" with Sebastian. He also explains that Sebastian is the one who "built a wall" between Sebastian and the narrator. Sebastian confesses that he had his own reservations about Sebastian because he was "an alpha," but now that he's in love with Sebastian, he can't "hold back" anymore.
