The band leader did say that this was an original song and a brief glance through the Twitter replies along with a quick Google search didn't turn up anything meaningful in terms of this being an existing song I could find a link to, so...

Someone did say that the songs she listens to kinda fits how she is feeling at the moment.

There's absolutely 0 risk the protagonist understand any confession in song anyhow given how utterly oblivious he is.

I think the girls could scream "I LOVE YOU" while stark naked and he would still be "what is all that about ?"

I'm gonna bet right now: Otomore is in the 95+% likability range.

I did. And I called it right.
