Paradise Villa (2001)

A teenage boy who is overly obsessed with online role-playing games gets his account hacked while playing. When he's finally able to connect to the game again, the character that he has spent so much time leveling up and searching rare items for is stripped of all it's experience and items. He then decides to rectify this matter by finding the other player who stole his inventory and weapons. This other player named Viagra apparently lives in a building called Paradise Villa. The people who live in this particular building all seem to have problems of their own.
