Two male protagonists
Zhan Yangli x Wen Lan
This is a world dominated by butterfly refining. Although the boy of the Wen family is well-dressed and well-fed, he was deemed "evil" because of the birthmark at the corner of his eye, and was abandoned at the age of five. In the following years, he felt different in himself. At the age of five, he met the second son of the Zhan family.
Purpose: Caring for butterflies is everyone's responsibility
