After dropping a hundred dollars each to head to the newest Miku Expo (which was a vocaloid concert), Chuuya pulled up to your apartment and took you to the concert.

After getting first in line, he rushed to the merch line and got a shirt, a few stickers, a poster, and a pair of glow sticks for each of you.

You and him quickly got the front area, right under the stage.

It had started a Chuuya was singing along to it, waving the sticks around. “Miku, Miku, ooeeoo!!”
