Came the following day, a problem arose with class 4/7's practice. Everyone didn't know how to play musical instruments except for Ethan. And thus, their first practice was a disaster, and they had to be thought-form scratch by Ethan, who was patient with everyone.
Even though Ethan felt like he was teaching grade school children.
No.
Even a grade school children weren't this hard to teach, mainly because they soaked all the knowledge while the adults were prone to resistance.
And mostly because Rever was playing his own style while Galahad broke his instruments because he didn't know how to exert enough force for his instrument to make a sound while Rin was playing asleep.
And at the side, Alfonse and Percival were still at each other's throats. While the latter mostly picked a fight with the former at every chance he got.
