My Roommate Stole My Membership Card

Evelyn owns the Ralton VIP8888 Black Card. Roommate Donna steals it to pose as an heiress and takes her ex, a fake rich kid. Evelyn enables SMS-verification; Donna's bill stalls, the manager reveals the true owner's million-dollar balance, and Carter (Blue Dragon heir) protects Evelyn. Donna falls into loan-shark debt and is expelled.
