Love at first sight and imprinting create the same effect on a person, but are two different things. Love at first sight can happen to anyone and everyone at anytime, while the latter only happens what they reach the age of 19. Do Kyungsoo is an eighteen year old submissive omega, not yet ready to imprint, but knows the difference between the two. So when transfer student Kim Jongin comes in with his pack and falls head over heels for the little omega, he knows just what to do. Reject him. But Jongin isn't giving up without a fight. Even if it includes other mateless alphas, and Kyungsoo's own pack. But what happens when Kyungsoo's past catches up to him? Will an alpha be willing to accept him after that? When Kyungsoo's 19th birthday gets closer, everyone gets excited and nervous. Especially a certain alpha.
