本菇凉我已长大
[bĕn gū liáng wŏ yĭ zhăng dà]
Translation would be 'I, this girl, have grown up'. Using a somewhat playful term for girls '菇凉 (girl)', it signifies entering adulthood and accepting responsibility while keeping youthful charm. Shows pride in maturity but also retaining childlike innocence or cheerfulness.
