i don't get the sending mail comparition, maybe verses a little, but chorus oO
it seems for me like a kiss'o'kill song (not exactly the same, but slow verse + strong dramatic chorus type)
i love chorus, because ive only listened to it twice, and I still remember how it goes~ so it got stucked in my head.
but verses (or this verse) is just out of the song. It's really blossom-like, but blossom was better still

they were not that cutesy.
