Oikawa had no idea he was a father, after all, you never bothered to tell the volleyball star that he had a son. You met at a bar, and what was supposed to be just a one-night stand ended up resulting in a son. When you found out you were pregnant, you immediately cut off the little contact you had with Oikawa, you just didn't want to get too involved, he's a famous volleyball player, you didn't want to ruin his career with an unwanted child.

You went through it all alone, and now your son was two months old, he was the spitting image of his father. He would never know that he had a son, but the media had other plans, being a public person, everything Oikawa did became a topic, and some people in this field, after looking into his life, discovered you, and immediately released the news 'Volleyball star Oikawa has a son?'

He didn't expect to find out he had a son from the gossip pages. He went to your house, a mix of emotions and knocked on your door, as soon as you opened it, he was faced with the scene of you holding the baby in your arms.

"I think you owe me some explanations, don't you?"
