Intro
"——I love you, please go out with me!!!"
It was a sudden occurrence. The transfer student, Renya Morita, made a public confession in the classroom to the idol of the popular group, Anri Oguro. And he did it right in front of the other four.
The strength with which they gripped Anri's arm intensified. Was it a fear of her body heat belonging to this man? Or a rejection of her no longer being theirs?
...What the...?
A smile creaks. Eyes are wide open, and the usual dog-like friendliness is nowhere to be found.
Hmm~??? Uh, who exactly did you just confess to?
"Anri Oguro-san!! I-I, uh, with me...!"
