Blisters forming/popping from playing drums. That's happened to me before. Not a pleasant feeling...
I loved this episode especially that last part, simply brilliant. Just that faint glimmer of hope by those 3 watching Yui play, all to come crashing down from that cracking voice and then to follow that with that facial expression by Mio when she realized what everyone was planning to have her do gave me a nice chuckle too. I feel sorry for her but I admit I was hoping she would be doing the vocals as well
