Grammar
N5AI-drafted〜ね/〜よ
right? / I tell you (sentence-final particles)
Formation
普通形・丁寧形 + ね/よ(文末)
Usage
ね seeks agreement or confirmation from the listener, or shares a feeling the speaker assumes both people have. よ tells the listener something new, or emphasises the speaker's opinion or warning. Using よ with information the listener obviously already knows can sound pushy, and leaving out ね in small talk can sound cold. They are mainly spoken; the combination よね softens よ by inviting confirmation.
