Birthday Wish

TL;DR Miyako got younger after taking some medicine

Reality shock...

It's not your fault, it's my fault for drinking it without knowing what it was

Sorry Miyako... It's your birthday, and I got you turned into this...

Seeing Miyako like this makes me think back to when I was still young...

I was once this small too

Sensei, this is my birthday wish. Please drink this medicine.

Uh...

My. Birthday. Wish.
