Chisato is a beautiful 35 year old writer (who looks like 18 really), father of Riju, a cute 15 year old boy. Chisato's hobby is to drive away all of Riju's friends because he thinks they want to corrupt his precious child. So he shows his good side to these boys while he poisons the cake he brings them with a smile. However, there is one guy, Shunsuke, who doesn't fall for the tricks. But is Shunsuke really aiming for Riju? Who is that mysterious writer Chisato loves so much? And why is Chisato convinced that Riju's friends want to take advantage of him?
!!Contains Examples Of:
* AloofBigBrother: One of Chisato's older brothers ''threw a knife at him'' on their father's orders.
* DysfunctionalFamily: Chisato's family is definitely this. They're lucky they have their looks.
* [[GrandmaWhatMassiveHotnessYouHave Grandpa, What Massive Hotness You Have]]: Chihiro, Chisato's father and Riju's grandfather, looks like a (slightly) older version of Chisato.
* HairTriggerTemper: Chihiro threw a table when he was angry at Chisato, and Chisato himself isn't a very calm person, to say the least.
* IdleRich: Chisato's family owns an inn, which could explain why he never has money problems and can afford to live in a rather large house despite being a struggling writer.
* OlderThanTheyLook: Chisato's 35 and [[UpToEleven can get away with pretending to be a high school student.]]His father, Chihiro, definitely does not look like a grandfather.
* PapaWolf: Chisato to a rather ''extreme'' degree. He's convinced that anybody who becomes friends with Riju wants to take advantage of him sexually and will do ANYTHING to drive said friends away.
* [[spoiler: RapeAsBackstory: The entire reason behind Chisato's twisted personality is that he was violently raped by an upperclassman whom had been his friend and mentor when he was in high school. What makes it worse is that this same upperclassman is ''Shunsuke's father''.]]
* SoBeautifulItsACurse: Chisato's good looks have resulted in a lot of unwanted attention...though he [[ObliviousToLove rarely notices]] and [[ComicallyMissingThePoint tends to assume that anyone who hits on him is actually trying to making a move on Riju.]]
* UncannyFamilyResemblance: Chisato, his brothers and Chihiro all look a lot like each other. Chihiro is even able to make himself look almost exactly the same as Chisato!
* UnknownCharacter: Riju's and Shunsuke's mothers are only mentioned and never actually seen.
