Nuo is a little boy who was born with nevus flammeus on the right side of his face. To comfort him, his mother always told him it was because a “red butterfly” stopped on his face.

Nuo loved studying insects. One summer holiday by his grandma in the countryside, he enjoyed a great time observing and collecting insects. He made a few friends there. However, after discovering the “red butterfly” on his face, his friends began to feel afraid of him, guessing he was a “little freak” who would “kill” insects and even locked a red butterfly in his own body….

Could the misunderstanding be cleared up and the friendship restored?
