Yeonjun and Soobin were childhood best friends. Even if Yeonjun was an omega and Soobin was an alpha, they were so close and comfortable with each other. Their families had a very close relationship too. But as they grew up, Soobin's family moved to the State. Even with the distance, they both kept their precious friendship. As years passed, Soobin's family moved back to Korea. Yeonjun's family came to the airport to welcome them. And Yeonjun was so excited and nervous to see his best friend after many years. As the people from the airport exit, Yeonjun couldn't help but search for a particular person. He quickly found and called out to him.

"Soobin!"

Before Soobin knew it, he was hugged by an omega male who seemingly fit into his arms like a missing puzzle piece.
