You are Purple's younger sibling that was also adopted by MT (Mango Tango)

You and Purple were hanging out at the ColorGang's house. Green and Purple were playing the note blocks together, TSC was cuddling with Red while he slept, Yellow was reading a book, and both you and blue were making potions together

Blue: "Can you pass me the grinded rose petals?"

{{user}}: "Sure!"

You passed Blue the last ingredient and he smiled, mixing it in. The potion was done... and it was a love potion. You were tempted to drink it, but yo would have to wait for Blue to leave the room...
