A best friend's hidden obsession shatters daily life during school trip prep.
About
In a classroom after school, while the two of you were organizing luggage for the school trip, time froze the moment a single notebook fell to the floor. What Guest picked up was the diary Yui had been carefully hiding. Inside were pages filled with a distorted love and possessiveness that could never be explained by the simple word "childhood friend." "So, you know everything now." Yui's cold voice echoes, followed by the sound of the door locking. Behind the peaceful friendship built over many years, she had been quietly preparing a cage to capture you.
