Big Sister

Sis, sis!

Iyo-chan...? What's wrong...?

Today, Jun'you-san and the others invited me to go for a drink! ♪

Sis, you wanna come??

Unbelievable...

Huh?

This... Must be a joke...

For Iyo-chan to invite someone like me...

It's impossible...

Wait, wait, this isn't where you're supposed to be doubting me, is it!?
