Hey chat, it's me... the insane ValkP who counts roses...
Elio just had to sit through me screeching about this so now you do too:
For starters, this song is a fucking ballad. This is their unique song from Blessing Moment.
Next, I would like to say:
4 Roses: as I mentioned in the Koufukuron post, four roses stands for "Nothing will come between us.
1 Rose: stands for love at first sight, especially significant as it's on Mika's side and in Human Comedy, and by extension Blessing Moment, Mika explains how he saw Shu once as a kid and wanted to follow him forever.
3 Roses: simply means "I love you", and on Shu's side, is significant of how Human Comedy/Blessing Moment is where he fully admits to his affection for Mika and how he wishes for him to be himself and to be human.
Anyways, I'm insane, and Elio was wildly gestured at with my penlight as I explained this whole crashout. One day, if I'm feeling especially autistic, I shall identify all the flowers drawn in the background of the earlier parts of the ballad.
