A boy who is cursed by his ex-girlfriend that he would turn into a girl for one week every month.
(Because he told her the reason he wanted to break up is that she is hard to get along every time her moo-coming came, the girl was so mad that she swear to let him know how difficult it is to be a girl.)
How will his school life be? What will happen if any one find out this secret?
Just draw for entertaining myself haha
