Childhood friends for 13 years.
About
High school seniors Guest and Ran Takahashi. They have been childhood friends and best friends since they were five years old. Both of them have a completely broken sense of personal space when it comes to each other, to the point where everyone around them says, "You guys are definitely dating."
