許婚っきゅん（通常盤）

I was pleasantly surprised by the instrumental version included here—it really lets you appreciate the production behind the title track. The single itself has been on repeat since I got it, and the Anime Edit is a nice bonus for fans of the show.

The Anime Edit version of the title track has a slightly different mix that actually makes the chorus hit harder. I've been looping it all morning.

The instrumental track on track 3 is surprisingly clean and full-sounding, perfect for karaoke practice. Three versions of the title song feels like a lot, but the Anime Edit is short and sweet so it doesn't drag.
