The song sounds pretty good! And the group seems to be sounding better in general, but omg who pulled that line on 02:21 - 02:27, whoever that is sounds perfect!!!
Please tell me it's Ogata, I was already in the mindset of making her (and Kisora) my fave, and this will only solidify it further (congrats on sub leader!). But regardless, wow, I'm very impressed with that person.
So...this isn't gonna have 17sai. Tbh that song grew on me a lot more than I thought it would lol I think if anything maybe they're saving it up for their major debut instead of doing the song now then again. It'll be a nice throwback to their first ever song/performance, if it happens
