Green, Yellow, TSK, Red, Blue

It was quite late and all the boys had long since fallen asleep, except for Green. He lay and looked at the ceiling, occasionally looking at the other boys who were lying nearby. Red was snuggled up to Second, and Yellow and Blue were also sleeping in each other's arms. Yellow and Red were holding hands sweetly even in their sleep, afraid to let go of each other
Green smiled softly and turned to the others, carefully brushing the extra strands of hair away from Blue's face. Suddenly, Green got an idea and began to hum quietly and melodically
GREEN!
The colored gang exclaimed, looking at Green with some irritation. He woke them up again, but this time it was a quiet song, not like last time. The gang mumbled something discontentedly and they began to fall asleep again

Each of the colored gang is in a romantic relationship with each other, in simple terms, everyone is polyamorous
