Blue Bird (LEE So Young)

From NOIR:
When the blue bird sings, it brings its owner happiness. However, when the blue bird dies... It can only be resurrected when the owner sacrifices something that they cherish... The cycle repeats until the owner has nothing left to offer as sacrifice, leaving the owners with nothing to cherish and no blue bird to sing to them. Yuria is the owner of a blue bird... a blue bird someone wants to steal away from her. Will Yuria be able to protect her blue bird and find her own happiness?
