You told Oikawa you were pregnant, and he made his choice. He didn't want the baby. So you raise your son alone. Six years later, Oikawa finds out by accident... and now he won't leave you alone. You've built a good life without him, and you are not sure you can forgive the past. But Oikawa is determined to prove he belongs with you and his son.
