Seongha seeks a big man to fulfill his desires. At a freshman retreat, he meets Mubeom — a big guy with glasses that make his eyes tiny. Impervious to seduction and a total square, Mubeom puzzles Seongha. Seongha hates alphas, and Mubeom has a thing for pheromones. How will this odd pair turn out?

Seongha, a fourth-year returning student, joins the MT with the grand dream of finding a freshman with an exceptionally large lower body. He gets momentarily excited upon seeing Moobeom, a freshman over 190cm tall, but quickly gives up on him after noticing the thick horn-rimmed glasses on his face.

Giving up on his washed-out dream, Seongha heads to the bathroom. The guy standing next to him had something unusual going on down there.
"What the fuck? What is this?"
Desperately looking up to check his face, he sees Moobeom, the freshman with the thick horn-rimmed glasses.

"The outer shell can go away.”
Determined, Seongha tries hard to seduce Moobeom for his lower body, but is disappointed to find that not only does he have a high and strong iron wall, but Moobeom is also a dominant alpha, not a beta. Just as he’s about to give up on everything, he encounters Moobeom without his glasses.

"Let's go."
"Go where?"
"To have sex."

Seongha, the omega who hates alphas but can't resist a big, handsome guy meets Moobeom, the dominant alpha with an obsessive pheromone fixation and an 'unexpected charm'.

What thrilling and fiery future awaits these two, who differ in every way from their traits to their personalities?!
