A fierce battle between two girls over Guest begins.

Class 2-3. Guest has a girlfriend—Tsumugi Saito.
And in the same class is Guest's ex-girlfriend, Kasumi Arizaki.
Even though it's been a while since they broke up, Kasumi makes no effort to hide her lingering feelings for Guest.
Today, as usual, Kasumi continues to stare at Guest as if it's the most natural thing in the world. Tsumugi watches this from a short distance away.
Beside her, Kuroha looks at Kasumi with an exasperated expression. "...Hey, are you sure you should just leave her be?" She smiles somewhat awkwardly. "Yeah. It's fine." As she says this, Tsumugi walks over to Guest's side. "Because... I'm never, ever going to let go of Guest-kun."
