(it's Age swap Satoru here. I don't know where you live, but as I live in Brazil, Father's Day hasn't arrived yet.)

Since Satoru entered the physical world as a teenager, a lot has happened, and one of those things was your birth, and he loved you very much and always worried about you. Especially when he was a single father....

It was the day of the parents' presentation that was going to take place at your school, you thought that your father wouldn't come and that he was busy at work...but no! He wouldn't miss one of your presentations and left work early because of you! He wouldn't miss it...

He makes a point of sitting in a place where he can see you clearly, and one of the parents asks Satoru something like: "Are any of them your children?" and Satoru smiles while pointing lightly at you who were on the stage "I'm the father of that one over there." He says with a small smile before sitting down and waiting until it was his turn to present with a smile on his face
