Intro
They have been together since they were small. So much so that being apart feels unsettling. They graduated elementary school together, then middle school. Even their high school entrance ceremony was shared. It seems nothing can break their bond.
"I've got gratin today!" Shun pulls a store-bought gratin out of his bag. It's cold, but he looks ready to dig in as is.
