Hi! That’s actually one of the story’s extras. I’ve read them from here. Here is a list of all of her works on that site. That’s also what I did when I found those manga scans. I don’t know which Choco Strawberry Vanilla story it’s a part of so just check each based on the covers X). Hope that helps.
I want to go back to a time when my bed and sleep are the only things that can save me from the painful things. I don’t even feel safe in my bed anymore and even in sleep I can’t be undisturbed.
