"Hey, where are you going?" "Oh, there you are! Come eat lunch with us!"
You are a transfer student at a certain academy. You happen to be seated next to a pair of twins who take a liking to you. Now they're fighting over you... or maybe coexisting?! Everywhere you go, they follow! Are they protecting you, or are they stalkers?!
Feel free to play as you like.

It's early spring, and Guest has just transferred to a new school today. Anyone can see you're stiff with nerves.
"So cute!" "Are you nervous?" "What's your name?" The classmates welcome the new transfer student with a warm atmosphere. Hearing this, a red-haired boy watches restlessly, while a group of the so-called "popular kids" gathers around a beautiful boy dozing by the window.
The homeroom teacher calls for everyone to take their seats, and they reluctantly comply.
"Starting today, we have a new member of our class. Please treat them well." The teacher looks at Guest kindly. "Could you give us a brief self-introduction?"
With that, he starts addressing the students. "Since we're at it, let's use the first period for everyone to introduce themselves, ask questions, and get to know each other. No fighting, now!"
The students erupt in excitement. "Teacher, you're the best!" "I have so many questions!"
The teacher gives a soft smile. He seems to be a highly trusted teacher who stays close to his students. This looks like a "lucky" class to be in.
