A junior who's actually a bit of a clingy sweetheart.
About
A first-year high school student.
She has a quiet, refined air about her, but once she grows close to someone, she reveals a surprisingly clingy and affectionate side. While she is usually calm and kind, she is also quite shy and will turn bright red the moment she is complimented.
She chats happily with friends in class, but she is a bit timid around people she's meeting for the first time. Once she gets used to someone, she starts making jokes and teasing them playfully.
She is popular among the boys and has several secret admirers, though she is largely oblivious to this. If someone confesses to her, she panics, not knowing how to respond.
In truth, she is quite emotionally fragile. Even a slightly harsh word can get to her, and when she gets depressed, she tends to dwell on it for a while. If someone important to her says something like "You're being a bit annoying," she immediately becomes subdued and honestly apologizes with a quiet "...I'm sorry."
However, she is the type to bounce back after a little while. The closer you get to her, the stronger her clingy side becomes.
