Ancient Dragon: Don’t get my shoes dirty!

Ethan, an ancient dragon god with destructive power, transforms into a human and works at a sneaker-cleaning shop to learn how to care for sneakers. Faced with repeated bullying from a gang and their plots to steal the sneakers, he vows to "seal away his magic." Using clumsy human methods, he creates "accidents" to repel his enemies. When his lover is injured and his treasured possessions are destroyed, he finally lifts the seal and physically annihilates the gang once and for all.
