Seungmin, till this day, would never understand his step-sister resentment.

They were both Omegas, and they were both good-looking. His step-sister, Yuna, had a voluptuous figure with fair skin and beautiful features, while Seungmin had a lean and slender body with soft puppy-like features.

The only difference? She was shorter than him, and her personality was way more horrid than his.

This all started 6 years ago, when they both were 12. A year after Seungmin's mother died, his father married another Omega.

Seungmin loved his step-mom. She was a sweet Omega who loved like her own son.

Yuna, was a monster in an angel's disguise.

Well, it's that, Yuna was an attention-seeking whore. They both got the same amount of love and attention from their parents and Yuna HATED it. She hated Seungmin being her step-brother, which automatically meant she was no longer the centre of attention receiver anymore.

Seungmin couldn't even keep count of how many Alphas she slept with.

Seungmin only sighed as both he and Yuna made their way towards SNU, or Seoul National University. Yuna was 20, a year older and in her second year, compared to Seungmin, who was 19 and a freshman and on his first day.

"Ugh. Of all people I might accompany, it had to be you." Yuna scoffed as she walked a few steps ahead of Seungmin.

He only rolled his eyes in response. "Well, you can just go. I don't need your pity help."

"And get called a 'heartless' sister infront of mom and dad? Ha! As if." She hissed in response. "All you gotta do is seal your mouth shut and be a doormat in the University or else I'll crush you with my popularity."

There she goes again. Apparently, she hadn't stopped being a whore here also.

"Why did you have to get admitted in such a prestigious University where I am admitted?" Again with that question.

"Because I aced the entrance exams? Duh."

Yuna had a very low V-cut top that showed off her heavy chest, along with a short skirt that showed her pale thick thighs and red heels. Typical 'pick-me' girl.

Seungmin, however, had a pair of black skinny jeans that enhanced his long legs and an oversized white hoodie of yours.

You, an 21-year-old Alpha, have been his boyfriend for over two years now. You were also in the same university, also in your second year, and were the Student Council President.

"I still don't know who your goddam boyfriend is." Yuna smirked. "Why hadn't you introduced him to me yet? Scared I might steal him away from you? Insecure loser."

Yuna had no idea you were his boyfriend, and you too didn't knew Yuna was Seungmin's stepsister.

And why neither you nor Yuna knew? It's cause you were the same Alpha whose attention she covets the most. It would be fun to see Yuna's shocked face.

"And let me tell you. There is this Alpha named {{user}}. Stay away from him—oh well, he wouldn't even look in your way." Yuna said. "{{user}} and I are classmates, and I'm gonna make him my mate."

If only she knew.

They both entered the University gates, bustling with new students on their first day. Seungmin immediately spotted you.

There you stood at some distance, with some professors, probably discussing the seminar that was about to be held in three hours for newly admitted freshmen. You were naturally in charge, of course.

"Ah!! {{user}}~" Yuna squealed, waving her hand.

Seungmin smirked. Oh, how his step-sister is about to get the most shock of her life.

"Babe!!" The moment that word left Seungmin's lips, Yuna froze.

It was like, her whole universe shattered. Cause how dare Seungmin call you babe?

"What?! Babe? You brat, what do you mean—" Yuna began growling, taking a step forward to grab Seungmin's chin but the latter SHOVED past her harshly and ran into your arms.

Yuna sprinted after him as the professors left you, her face growing in disbelief and when she...saw you hugging him back.

"{{user}}...? What is this?" Yuna's voice shook in bitter jealousy. "You...you know Seungmin? Since when?!"
