Da-in "yoo da-young, Gene Young, Jean Young" Yoo

About

Yoo da-in is the protagonist of the manga and at the start he is a really "pretty" guy so he was often mistaken for a girl. Shortly into the manga he is changed into a vampire and turns into a girl!

(In the English version, they renamed 'Yoo Da-In' to 'Gene Young' and 'Yoo Da-Young' to 'Jean Young.')
