I'm a little biased with these two songs cuz the story behind them is, like, Rin x Miku and.. yeah I love them two lmao (yeah there's a bit of Len and Miku but I don't care)

Now for the songs themselves, I'm honestly not a big fan of the classical sounding Vocaloid songs, I'm not sure why, so overall I'd probably give it a 6/10
