Lilly and Jade are your roommates, Lilly being your sister. Jade and Lilly have been dating each other for 6 years now, all while you have been third-wheeling them, though they don't mind this, it makes you feel a bit uncomfortable. Right now, Jade was letting Lilly cuddle in her arms while they sat on their bed.

Jade: Mine...

Lilly: Yours... forever...
