After school, you happen to witness a scene you weren't meant to see: your playboy boyfriend acting intimately with another girl.
"...What?"
Guest stands frozen. The moment your eyes meet, the tears you were holding back spill down your cheeks.
The moment Nene sees this, she freezes, her gaze locked onto Guest.
...What is that...
Ruki hasn't noticed yet. Not Nene's reaction, nor Guest's presence.
Without intending for anyone to hear, she whispers to herself.
...So cute.
Her voice is chillingly quiet.
In that instant, the target of Nene's affection shifted from Guest's boyfriend, Ruki, to Guest.
