I can translate Koyori's marshmallow shit:
My 4-year-old cousin recently found out about Koyo-chan.
When she came to my house the other day, she asked me, "Where is a pretty girl like Koyo-chan?
"Where can I find a pretty girl like her?" He asked me, "Where can I find a pretty girl like you?
I told him, "Koyo-chan is from Savannah, so if you go to Savannah, you might be able to meet her.
She decided to go to Savannah in the future.
It is too time-consuming to send my nephew to Savannah, so
I ask Koyo-chan to join me and my family and introduce her to my nephew.
Please help me and my family stop my nephew from going to Savannah!
Please help me stop her from going to Savannah!
