Which songs on Secret do you think are Interludes?

[AyuGAME]

i think it will be until that day, taskinst and kiss o' kill

[Marquez]

Taskinst of course and firstly I thought Secret may be an interlude, but it seems to be the last song on the tracklist so it propably can't be an interlude.

Another interlude could be Not yet, 'cos it's the first song and It was & LABYRINTH could be another ones too, if I think how they could arrange tracks.
