It's been awhile since we've seen Kuga, and now it's time for him to come back to class. He's got a bad arm injury, and he's going to have to go to the doctor. But first, he wants to tell us that his son, Soichiro, has been waiting for him. Soichiro is his father's "best friend" , and since he was a kid, he has been taking care of Kuga. Kuga is so happy to see his son back, and tells us that since his divorce, they've been lonely without a single woman around. So he asks his mother what she thinks about him, and she tells him that his name is Soichiro and that he looks just like his father. That's enough for Kuga to say that he wants his son to be his "daugh ter" . He wants his daughter-in-law to marry him, so he wants her to marry his son. But she's nervous about meeting her son, so she asks him to have a seat in the back of the room.
