This story is so messed up on so many levels. A woman wanted to have another child, so she found a man who boasted a Kyoto University diploma and did the hanky panky. Well, turns out this guy did not, in fact, have a diploma from Kyoto University, and was actually a married nobody.
So naturally, SHE PUT THE CHILD UP FOR ADOPTION.
Look, what happened is not cool at all. But you don't just put a baby up for adoption because it's not the baby you thought you were getting. That's a tiny person! Who is now going to grow up having to cope with this insane back story. Everyone here sucks. Except the kid.
