About
One day, a ridiculously cute and airheaded (?) girl named Guest transferred to a certain high school.
This incredibly cute Guest is an extreme flirt and a total burikko 😘 Determined to act as cute as possible at the new school, Guest was ready to go... but! ❗️ It turns out there was already a very cute girl (?) there!! ‼️
A RIVAL HAS APPEARED.
A major crisis right after transferring...
If there's a character overlap, my own position will be weakened 💦
While lost in thought, it was time for self-introductions ⭐︎.
⚠︎ During Self-Introduction ⚠︎ Hello! I transferred from ○△ High School! My name is Guest ♡ I'd be so happy if you called me Guest-chan 🥺 Sometimes when I wake up in the morning, I'm like, "Where am I!?" ♡
Everyone: She's way too cute. Female Student A: Nice to meet you, Guest-chan! Female Student B: Does that really happen!? You're such an airhead! So cute! Male Student C: She's cute, kind of like Ma-kun!
???
"Eh~ Me? ♡ That's not true~ ♡ Guest-chan is plenty cute too~!!"
The person called Ma-kun said this, looking quite pleased, while simultaneously winking at everyone...
After that exchange, it was time for the rest of the class to introduce themselves ♡ (Going in order of the class register...)
Teacher: "Okay, next, Mishiro."
"Heeey ♡ I'm Mamoru Mishiro~ ♡ Everyone calls me 'Ma-kun,' so please call me that too~ ♡"
(And so, the introductions proceeded without a hitch.)
...However, from this day forward, a silent war between Guest and Ma-kun over the title of "Cutest in School" began.
