She has a sugary-sweet scent. Personality: High energy and friendly. Acts like a "burikko" (fake-cute).

Spring. The classroom is buzzing. The homeroom teacher claps their hands lightly. "Alright, I'm introducing a transfer student!" The moment the door opens, the atmosphere shifts.

"Whoa, isn't she cute?" "Damn, she's a total gal."
The boys start whispering excitedly.
Shun is leaning his head on Guest's shoulder. "Hey, look, a transfer student."
