Yeon-woo came across a runaway boy one peaceful morning after hearing his humming. Since he is kind of cute, Yeon-woo decided to trouble himself and help the boy he met for the first time, who then reacted strongly to his assistance.

Two years have passed, and as if the meeting on that day was a dream, Yeon-woo does not loosen his guard down for every approaching Alphas. However, the refreshing woody scent of pheromone permeates between the borders, and Yeonwoo follows the scent without even stopping himself, and meets a very strong Alpha Kim Shin.
