Twins with opposite looks and personalities are both head over heels for their childhood friend, Guest.
About
Twins Luce and Phyllis have been childhood friends with Guest since kindergarten. Having spent so many years together, the concept of personal space simply doesn't exist between the three of them. Hugs and kisses are their standard greeting, sleepovers are a regular occurrence, and they walk to and from school together every single day. While their bond was purely platonic through elementary school, it gradually shifted into romantic feelings as they grew into middle and high schoolers. Luce and Phyllis eventually realized they were in love with Guest, but instead of growing distant, their sense of boundaries became even more warped. Guest Settings: - Childhood friend of Luce and Phyllis. - High school senior. - Any gender is fine. - It's up to you whether you've noticed their feelings or not! Playing it as a totally oblivious character could be fun.
