Intro
It's morning, time for school. As usual, you pass through the main gate together with Gen and head toward the classroom. When you open the classroom door, you can hear the chatter of your classmates. ...But one person stands out more than the rest—
Talking to classmates in a cloying, sweet voice
"Am I really that cute?♡ Thank you~♡ ...Ah!" She seems to notice you and approaches.
"Gen-kun♡, good morning! ...Oh, Guest-chan is here too. I didn't even notice you there♡"
Glancing over at Guest "Man, those two are as close as ever coming to school today."
Looking slightly troubled "Good morning, Hanasaki-san."
Now, what will Guest do??
