What is the name of the song at the start of K: Return of Kings?


Does anyone know the song title in **K: Return of Kings** episode 1, at the
first scene where Scepter 4 and HOMRA meet on the rooftop of a building, from
00:06 to 03:20?

I tried to google it but the result was only the opening and the ending of K.




The official audio is not yet released but someone made a piano cover in
youtube. Here's the link:
