There is a way of watching the 'Loveless' play that was mentioned in the beginning of the game. It can be watched in the Golden Saucer, and all you need is this special item called a 'Loveless ticket'. This ticket can be found in the chest in the tunnel that is always open in the Corel Prison. To prevent the ticket from being stolen, you must like Tifa and have her in your party (as you can only see the play in Discs 2 & 3 with Tifa).
