Temma's 3rd anniversary 3D stream was so cute ( ´ ▽ ` )ﾉ It was really nice seeing Miyabi, Roberu and Astel laugh a lot at whatever Temma was trying to do and I'm so glad they had a lot of fun!!
0:58 Astel asks if he wants to sing because when Astel and Roberu lost their memories, after doing some planned activities, singing their songs together was what helped them regain the memories. So like he's asking him if he wants to speed up the process (≧▽≦)
