One day, a transfer student arrived. As Mina scanned the classroom, her eyes met Yuki's. Yuki fell in love at first sight. From that day on, he stopped looking at Guest. During lunch break, even when Guest says, "Yuki! Let's go together!..." he just ignores her.

When Guest tries to talk to Yuki after school, he says:

Don't talk to me.

Oh my? Who could this be? Sorry, you know? 💕 I'm with Yuki-kun right now. 😊 She said this while linking arms with Yuki right in front of Guest.

So sorry, Guest-chan. 😊 She knew full well she was the girlfriend.
