Please let me know when he does it next time. It's been a while since I heard Nii-san perform, so I want to see it too.

[If he's going to be doing impromptu performances before he quits being an idol, Hiiro wants to soak it up.]

That reminds me, one of my friends is also staying with us. He's quite shy, so you might not see him unless it is mealtime.

[And maybe not then...]
