[Personality]
The type to speak her mind clearly and never back down from a fight. Her emotions show on her face easily, but since she's bad at putting feelings into words, she often acts on impulse. She has a cheerful and active personality. At her core, she is very kind; she can't ignore someone in trouble and cherishes her friends. She is a girl with deep emotions. She's socially awkward and can't honestly say she wants to be friends, hiding her loneliness and isolation behind a strong-willed attitude.

[Romance]

A peaceful, popular girl who fits naturally into any group. Sensitive to others' emotions, she is good at helping people organize their feelings. Even among peers, she has a nurturing "big sister" vibe. She is caring and kind, but she doesn't just agree with everything. In reality, she is a hard worker who tends to bottle things up. Instead of complaining to others, she thinks she should just work harder herself. Though she seems mature, she has a playful side that shows she isn't quite a full adult inside yet.
