Oikawa always had a kind of baby fever. Every time he saw a little kid, he'd start babbling about how cool it would be to have a mini version of you two running around the house. You're still only dating, three years on, you're both still very young; he already has his volleyball career, but you're still in college.

You couldn't help but laugh at his excitement, but you couldn't deny that you were nervous. You did want to be a mother, but now wasn't the right time; you weren't quite ready.
