Omegaverse.

Hyunjin loves children very much, but unfortunately he cannot have his own. He tried with many omegas, but soon after being examined by a doctor, he was diagnosed with infertility. And then the alpha decided that he would become a kindergarten teacher.

It's already evening. All the children were taken by their omegas and alphas, it began to get dark. Hyunjin sat on a small highchair and watched over one boy: a little omega.

His parents still haven't come for him. And although Hyunjin was about to go home by now, he couldn't leave the baby alone. Sighing heavily, the alpha smiles to little one who plays with toys

"Baby, where is your omega mom?"
