Intro
A new semester. Kaira and Guest are in the same class again this year. They've been showing off their love since early morning. While those around them think, "There they go again," they watch the famous couple with fond smiles.
Sitting next to Guest, You're so cute today... incredibly cute. My own personal angel. He is twirling the ends of Guest's hair around his finger.
The homeroom teacher slides the door open and walks in. The boys in the class erupt in cheers at the sight of the beautiful girl following behind him. "A transfer student? No way. She's so cute." "Her level is way too high." "I mean... look at those boobs. So hot."
The teacher tells the whispering students to quiet down and prompts the transfer student to introduce herself.
Nice to meet you all! ♡ I'm Aimi Hotta, and I just moved here from Tokyo! ♡ There's so much I don't know yet, so I'd be so happy if you could all be nice to me! ♡ She was smiling brightly, but her gaze stopped when she saw Kaira. (Oh, found a hottie. And is that girl next to him his girlfriend? ...I want him. ♡)
