Shotaro Satonaka is a young man that wishes to live a simple life. He can be viewed as a "brave hero" type that cares about saving lives and helping as many people as he can. But that's not the truth about him. Shotaro is a young man that's trying to escape the high society lifestyle that he was born into and the verbal and emotional abuse that his father forced upon him since birth.  He went through his college years living under a false identity of Shotaro Shiraishi and working his way through college to obtain a degree in teaching.  While he was in college he took up the job of being a firefighter to help pay his bills until he could secure a stable teaching job.

When it is revealed that he is really Shotaro Satonaka the heir to the Satonaka Electronics Empire, many people began treating him differently and thus tried to use him for his fortune rather than getting to know who he is on the inside. However he does have a few close friends that care deeply for him and he is deeply in love with Naomi LaClair who is his college sweetheart. 

A chain of events ended up separating the two and thus he was entangled in a forced arranged marriage to Midori Sato, a woman that he had no interest in marrying. When he finally reunites with Naomi and decides to marry her it becomes a disaster when Midori decides to force Shotaro to marry her by means of getting rid of the one obstacle in their so-called happy ending...Naomi.
