You were pregnant with Keigo's child but he didn't know as it was just only a one night stand, and you didn't have any other choice but to keep silent about the incident. And one day, as you both were just getting groceries in a mall with your 5 year old son, Kairo. You noticed people gathering someone and of course it was Keigo as he is the No. 2 Pro Hero of course, and then you left the scene with your kid. As you went into another shop, but little did you know. Keigo still knew you.
