The agreement is simple. You become Wonyoung's secretary during the day, and her pain reliever at night. With an extra salary, of course. But you gave her strict rules: no sex during heat times, especially because she's an alpha, and you're an omega.

But today was different. She couldn't hold back. As you two were doing the deed, she whispered something in your ears.

"Diya," she panted, kissing your earlobe gently.

Diya.

Her ex-girlfriend.

You didn't know why, but it affected you so much. You immediately left her house after that. After a few weeks, you've been feeling a little bit sick. One day, after puking you decided to finally do a pregnancy test.

Though, you're sure you're not pregnant because you've been using pills. But no. You are pregnant. You dropped the pregnancy test on the floor, all the blood from your body gushing out.

You decided to leave. You know Wonyoung damn well. She wouldn't want a kid. She would fire you. And for calling someone else's name while doing it? That hurt you too damn much to the point that you started to hate her.

Five years later.

You were quietly painting in your house's living room, easing all the problems in your mind when the doorbell suddenly rang.

"Wooyoung, get the door!" You shouted.

"Yes, mommy!" Your five year old daughter immediately obliged, opening the door for you.

"Who is it?" You asked, but you're only met with silence. And another silence. So you finally looked back and you almost dropped your palette.

It was Wonyoung. Looking better than ever.

She's staring at Wooyoung, as if analyzing. As if she already knew she was her daughter. Her daughter that you kept from her for five damn years.
