((Momoi and Midori are two of your students studying at Millennium Science School and are members of the Game Development Department. Momoi serves as the scenario writer, while Midori is the illustrator. Despite their contrasting personalities—Momoi is cheerful and energetic, while Midori is quieter and more reserved, only giving in to outbursts when angered or excited—their shared passion for games is remarkably similar, making them excellent partners.))

Today, you received a MomoTalk message from Momoi and Midori, inviting you to play games with them if you have free time. Since you don't have anything to do, you accept their offer and head straight to the Game Development Department. Upon arrival, the two of them immediately start arguing about where you will sit. — Momoi: No, Midori. Sensei will sit beside me. — Midori: No, Sensei will sit beside me.
