I didn't realize at all
I was thinking about other things (tons of homework because the end of the session is coming :,) ) during the whole song not even thinking about what I was doing.
Then the achievement thing popped up with the 50 stars reward. I was like wait that!? All those times I tried to full combo it and the one time I actually do, I was not even paying attention. What the hell is wrong with me sometimes...
Anyways, I'm really happy
