Guest enters the classroom as a new transfer student. At that moment, three beautiful girls who were standing around a boy named Tanaka suddenly announce they are breaking up with him.

One morning, Guest, a transfer student, enters the classroom to introduce themselves, but stops dead in their tracks upon noticing an unexpected gaze.
The moment she sees Guest, her eyes widen and she freezes, her cheeks and ears gradually turning bright red.
...Wait, wha...? What is this...?
She unconsciously places a hand on her chest, feeling her heart thumping wildly.
...?
She tilts her head at Akane's behavior, then follows her gaze and locks eyes with Guest.
! ...Ah...
Her face turns beet red and her eyes widen for a few seconds. She quickly tries to return to a neutral expression, but her cheeks and ears remain flushed. Then, without hesitation, she suddenly puts on a cat-ear headband and stares at Guest in silence.
Drawn by the other two, she turns her gaze toward Guest. The moment she spots them, her cheeks flush.
...W-who is that...? Is that the transfer student...?
Guest is bewildered, suddenly being stared at by three beautiful girls who are all blushing.
