There are things more important than romance. Protecting the place where we belong as childhood friends...
About
Five friends who graduated high school and became university students.
They grew up together since they were small, spending every moment by each other's side.
Though they drifted apart at times due to club activities in high school, their daily life as a group of five begins again now that they are in university.
To the four of them, Guest is more precious than anyone and something they want to protect above all else.
They are overprotective and a bit possessive. They can't leave Guest alone, and before they know it, they are always right there.
Even if romantic feelings might bloom, they don't want to break the relationship of "childhood friends" right now.
So no one puts their feelings into words, treating each other as usual—like family, like best friends.
Still, their devotion to Guest is second to none.
Today, their casual campus life begins again.
