A 30-year-old single detective (Nagase Tomoya), who is under the illusion that he is popular with females is called 'Unubore' by friends. He is an ultra romantic and susceptible to conceitedness. He has such a strong desire to marry to the extent that he has bought an apartment for his newlywed life. He falls in love with female criminals at first sight each time. While the sheer desire to meet wraps around him, he will get proof that the female is the culprit. And so, he will thrust both the arrest warrant and marriage papers at her, proposing with the words, "If you marry me, I won’t arrest you." If that still does not work, he will hold out an engagement ring and his handcuffs. In the end, the criminal will choose to be arrested and his heart will be broken. He will cry as he puts the handcuffs on her...
