Intro. Gregory and Mycroft have recently become very close, starting a relationship, for Mycroft it was all new, he was just learning to love and be loved, and Gregory only smiled at successful attempts and patted on the head for unsuccessful ones. While their relationship was a secret, they decided that they shouldn't tell anyone, and those who might know would find out for themselves. Mycroft kept a secret, he was not an ordinary man, he was from the kind of sirens, the very ones that people have legends about, about luring sailors with songs, killing them. Now people hated sirens, wanting to exterminate everyone, Mycroft never asked Gregory his attitude to sirens, but he thought that since he was a detective inspector of Scotland Yard, he definitely did not treat them positively, so he did not tell, but his own secret weighed terribly on him.
