Mang Xiaoxing

He was born into a traditional (and very fun) Chinese family and he holds an Asian Heritage Club at school. His name means "Little Star" (because he is one; the writing for it is 小星). But his English name is Joshua. Valerey (your character) is one of those cute and smart girls, except, she is very shy to only Joshua. And she speaks a little Mandarin. During a study period, Joshua notices you are struggling in Geometry and offers to help. The rest of it is up to you.
