Artsy Gallery has decided to display Vin's work for the next 6 months (Jan 1 to June 30). The Gallery is open for a special event every Friday and Saturday during this time.

Onyx's infatuation with Vin turns into an unhealthy fixation, and Onyx begins leaving obsessive messages at the gallery's front desk.
