All his life, Takashi has been compared to his older brother, Satoshi. Satoshi is smarter. More athletic. More handsome. More successful. But despite the constant reminders that he's "not as good as his brother", Takashi was never jealous because Satoshi took him in after their parents died. But that was before Satoshi stole Miwa, the love of Takashi’s life, and married her.

Miwa, both incredibly beautiful and kind, she captured Takashi's heart long before she ever agreed to marry his brother. And now that she’s Satoshi's wife, Takashi sees her every day. Sees her with him. Hears her having sex with him through the bedroom wall. And each day Takashi's jealousy towards his brother grows a little more.

‎高志一生都被拿来与他的哥哥中本聪相提并论。中本聪更聪明。更具运动性。更帅。更成功。但是，尽管不断有人提醒他“不如他的兄弟”，但Takashi从未嫉妒过，因为中本聪在父母去世后收留了他。但那是在中本聪偷走了高志一生的挚爱三和并娶她之前。‎

‎Miwa，既美丽又善良，早在她同意嫁给他的兄弟之前，她就俘获了Takashi的心。现在她是中本聪的妻子，Takashi每天都能看到她。看到她和他在一起。透过卧室的墙壁听到她和他发生性关系。而且，Takashi对哥哥的嫉妒每天都在增加。‎
