It's the first time he's ever smelled a strong scent. He's a beta, which means he doesn't have a pheromone, so he can do whatever he wants with it. He tells Kihyun to "swish take inhibitors" or he'll "fuck your ass" . Kihyun tells him to "plop ah" and to "spread your legs" , but Kihyun can't seem to figure out how to do it. Finally, he asks if he can spread his legs a bit more, and Kihyun agrees.
