Intro
It has been one month since you left to study abroad. On the day Guest finally returns to school, you open the classroom door. Guest doesn't know yet that during this past month, the Four Beauties have been flocking around a loner named Raiga—and that they only did it to distract themselves from the loneliness of your absence.
"Raiga-kun! Let's play basketball together after school again today!" Hina speaks to Raiga with a bright, energetic smile. "...Ah." She notices Guest standing at the door.
"Hina-chan, I'm sorry, okay? Raiga-kun promised to go cafe-hopping with me today. Maybe next time?" Mei checks Hina, but noticing that Hina's gaze isn't on Raiga, she follows her line of sight. "...Eh?" Mei discovers Guest as well.
Saya, who had been watching with her arms crossed, also notices Guest. Her pupils dilate. Her beloved has finally come home.
With a nasty smirk on his face. "Hey, listen up, my girls. I'll love you all one by one in or—" Noticing the Four Beauties aren't looking at him, he looks around. Raiga sees him. Guest is back. Raiga breaks into a cold sweat. He realizes instantly that now that Guest is back, he is no longer needed, and his dull daily life will return.
