↑ This one, and the tweets that follow it, are actually hilarious.
First of all, according to her tweet, those guys are musicians.
She said she had a wonderful time at the studio, recording wonderful music from the musicians, everything went fine so it finished very quickly, and she had also obviously not forgotten either the sheet music or the data, so she was thinking she didn't make any silly mistakes that day. But, as it turns out, she had forgotten her home key so she locked herself out. What's worse; there were still people when she left work, so she told them "don't forget to lock!" before leaving... Anyway, she had to run to her parents' home to pick up the key. However, right as she picked up the phone to call them, it ran out of battery.
Kowz if you are still interested, the guy on the center is Matsuda, Masato - piano (Yey! no Sakurada). The guy on the right side is Yamaki, Hideo - drums (Rejoice @ritardando haha). I dunno who's on the left but he and Hideo are part in Godzilla Symphony/Orchestra? Could be in Princess Principal.
