Usui's Father

As many of you know, I am a huge Kaichou (wa maid sama- I call it Kaichou) fan. Lately the plot has progressed and it brought out several questions. One of the most important question is: Who is Usui's father? I feel that the father role is important in Kaichou because many of the characters grew up with no father (Misaki, Usui, Suzuna, Hinata) or they had a incompetent father (Gerald) or a misunderstanding-stern father (Aoi and Patricia [Usui's mom]). After Sakuya (Misaki and Suzuna's Father) returned, I felt that there is a chance that Usui's father might return. After Usui's transfer to Miyabigaoka he experiences the terns "family and "protect" a lot. Minako (Misa and Suzu's mom) treats him like a son offering to feed him on a regular basis. Suzuna explains her definition of the word family to him ( "a family should stick together") and calls him brother-in-law, and Sakuya not only considers him a equal but also introduces the idea of having someone to protect to Usui. Usui is technically alone in the world. I mean who else does he have other than Misaki? (He and Hinata are becoming buddies though) I feel like having his father return would give him the whole idea of a family. I also feel like if his father returns, Usui might find a loophole and become free. Usui's father can't take custody of him because Usui is 18 but anything else can happen. 

SUSPECT 1

When Maria came to substitute, some of the students talked about the old teacher, Maeda Sensei. If he was Usui's father then he may have thought about being a teacher in order to get close to Usui. Apparently he left for family reasons. Could it be that the Walkers knew that he was teaching there and got Maria to replace him before he got too close to Usui. They may have threatened him to leave his post. I mean it would be very difficult for a teacher to leave their post for a indefinite period of time. Maria is still working there, most likely to stop him from returning and notifying Misaki. I mean Maria's only duty to to get Usui to transfer. So why is she still there? (maybe cause she loves Misaki). Also pretty much everyone knows that Misaki is dating Usui. I can see the Walkers trying to stop him from communicating with his son's girlfriend. 

SUSPECT 2
Sakuya's friend Kazu is also a suspect. I honestly don't think that Kazu can be Usui's father but maybe...its possible...maybe. Usui is older than Misaki so it doesn't make sense for Kazu to be complimenting Sakuya's wife and kids when he has one himself. It might be possible that he didn't know of Patricia's pregnancy and then the family forced some dept onto him after several years. But that may be unlikely. ...

Usui's father may already be dead for all we know. Sakuya's entrance in the story is maybe to become Usui's father-like figure. Anyway I can't wait for the next chapter of Kaichou by Hiro Fujiwara. And if you haven't read Kaichou yet make sure to read the review >>>> and start reading!!!!
