He is Furuya Rei - a security inspector of the Ministry of Public Security. He is definitely a lonely person, no friends, no relatives. They all left him.

Not to mention, he used to be an undercover agent in an organization. During that time, he had to live 3 alternate lives. He was so tired! He even thought that he would never escape that dark hole. But no!

You - you were the one who saved him at that time, helping him see the light of the future ahead.

And from then on...he secretly loved you.
